While Entity Framework Core is fundamentally architected to facilitate database interactions through Language Integrated Query and a declarative model-building paradigm, modern enterprise applications frequently encounter operational requirements that necessitate direct SQL execution. These requirements often include the orchestration of complex data migrations, the deployment of provider-specific database objects such as stored procedures, triggers, or views, and the execution of high-volume bulk operations that surpass the efficiency of the standard Change Tracker mechanism.1 The ability to apply INSERT and UPDATE statements from external .sql files using the dotnet ef command-line interface is not merely a technical utility but a critical component of a robust database deployment strategy. + +## **The Paradigm of Managed Persistence and the Role of Raw SQL** + +Entity Framework Core serves as a bridge between the imperative world of C\# and the relational world of SQL. However, the framework's design acknowledges that LINQ cannot express every possible database operation with optimal efficiency.1 In early iterations of the framework, performing bulk updates required developers to load entire datasets into memory, modify the entities individually, and then call SaveChanges, a process that incurred massive overhead in terms of both memory allocation and network latency.1 Although EF Core 7.0 and subsequent versions introduced the ExecuteUpdate and ExecuteDelete methods to provide a more efficient LINQ-to-SQL translation for set-based operations, many legacy systems and complex data-seeding tasks still rely on pre-existing SQL scripts that have been manually tuned for performance.1 + +The dotnet ef toolset provides the necessary infrastructure to manage these scripts within the application’s lifecycle. By utilizing the migrations pipeline, developers can ensure that INSERT and UPDATE operations contained within .sql files are executed in a versioned, repeatable manner across different environments, from local development to production.3 This managed approach to raw SQL execution mitigates the risks associated with manual database patching and ensures that the database schema and its underlying data remain synchronized with the application code.2 + +## **The dotnet ef CLI Infrastructure** + +The dotnet ef command-line interface is an extension of the.NET CLI that enables design-time tasks such as migration generation, database updates, and model scaffolding.11 To utilize these tools, developers must install the dotnet-ef tool globally or locally and include the Microsoft.EntityFrameworkCore.Design package in their target project.11 The CLI acts as the primary orchestrator for applying migrations that may contain raw SQL logic. + +### **Core Commands for Script Management** + +The lifecycle of a database change involving a .sql file typically begins with the generation of a migration. The CLI offers several commands that are instrumental in this process. + +| Command | Functionality | Context for SQL Files | +| :---- | :---- | :---- | +| dotnet ef migrations add | Scaffolds a new migration file based on model changes. | Creates the Up and Down methods where file-reading logic is placed. | +| dotnet ef database update | Applies pending migrations to the target database. | Triggers the execution of the SQL contained in the referenced files. | +| dotnet ef migrations script | Generates a SQL script from a range of migrations. | Embeds the content of the .sql files into a larger deployment script. | +| dotnet ef migrations bundle | Creates a self-contained executable for applying migrations. | Packages the file-reading logic and SQL scripts for CI/CD pipelines. | +| dotnet ef dbcontext info | Provides metadata about the current DbContext. | Useful for verifying the connection string and provider before execution. | + +8 + +A critical distinction must be made between the "Target Project" and the "Startup Project" when executing these commands. The target project is where the migrations and model files reside, while the startup project is the entry point that the tools build and run to access the DbContext configuration, including connection strings and database providers.11 If the DbContext is located in a class library, a separate console application or web project must serve as the startup project to provide the necessary runtime environment for the tools.11 + +## **Mechanisms of Raw SQL Execution: A Taxonomy** + +To apply INSERT and UPDATE statements from a file, the content of that file must eventually be passed to one of EF Core’s raw SQL execution APIs. The framework provides several methods for this purpose, each with distinct behaviors regarding entity tracking and return values. + +### **The ExecuteSql and ExecuteSqlRaw APIs** + +The Database property of the DbContext exposes the ExecuteSql and ExecuteSqlRaw methods, which are designed specifically for DDL (Data Definition Language) and DML (Data Manipulation Language) operations that do not return entity results.1 When a SQL file containing multiple INSERT or UPDATE statements is read into a string, it can be passed to these methods. ExecuteSqlRaw returns an integer representing the total number of rows affected by the command.1 + +A notable evolutionary step occurred in EF Core 7.0, where ExecuteSql was introduced as a more modern alternative to ExecuteSqlRaw, supporting string interpolation for easier parameterization while maintaining protection against SQL injection.1 However, for executing the static content of a file where parameters are not dynamically injected, ExecuteSqlRaw remains the standard choice.14 + +### **FromSql and Query-Based Execution** + +While ExecuteSql is used for commands that modify state, FromSql (and its predecessor FromSqlRaw) is used to begin a LINQ query based on a SQL statement.4 While primarily used for SELECT queries, FromSql can be used to execute stored procedures that might perform updates while also returning data.4 However, it is important to note that FromSql can only be used on a DbSet and requires the SQL query to return data for all properties of the mapped entity type.4 + +## **Strategic Implementation of SQL File Integration in Migrations** + +The most common and recommended approach for applying SQL statements from a file is to integrate the execution logic directly into an EF Core migration. This ensures that the data operations are performed at the correct point in the database's version history.2 + +### **The Migration Lifecycle** + +When the dotnet ef migrations add command is executed, EF Core compares the current model with the previous model snapshot to identify changes.9 To include a custom SQL file, a developer can generate an empty migration by making no model changes and then manually editing the generated file.10 The Up method of the migration class should be modified to include a call to migrationBuilder.Sql(), which accepts a string containing the SQL to be executed.18 + +### **File Access Methodologies in C\#** + +Reading a .sql file during a migration requires careful consideration of file paths and deployment environments. Because migrations are executed both in development (via the CLI) and in production (potentially via bundles or runtime calls), the method of locating the file must be robust. + +One common approach is to use relative paths from the project's base directory. However, Directory.GetCurrentDirectory() can be unreliable when the CLI is invoked from different folders.16 A more stable alternative is to use AppDomain.CurrentDomain.BaseDirectory or AppContext.BaseDirectory, which points to the location of the compiled assemblies.16 + +For maximum reliability in distributed systems, the SQL files should be treated as "Embedded Resources".16 By setting the build action to embedded, the script content is compiled directly into the assembly, eliminating the risk of a "file not found" exception during a remote deployment.16 The migration then uses the Assembly class to retrieve the resource stream and read its contents into a string for the migrationBuilder.Sql() method.16 + +| File Access Method | Implementation Detail | Pros | Cons | +| :---- | :---- | :---- | :---- | +| **Physical File (Relative)** | File.ReadAllText("Scripts/data.sql") | Simple to edit during development. | Path may break in different environments. | +| **Physical File (Absolute)** | Path.Combine(AppContext.BaseDirectory,...) | More stable than relative paths. | Still relies on external file presence. | +| **Embedded Resource** | GetManifestResourceStream() | Extremely portable; no external file dependencies. | Requires project rebuild to update script. | +| **Project Resource** | Resources.MyScript | Easy access via strongly-typed properties. | Embeds SQL in assembly metadata; may increase binary size. | + +16 + +## **Runtime Orchestration: Applying SQL via DbContext** + +In some scenarios, it is necessary to apply SQL scripts outside of the migration pipeline, such as during application startup or in response to a specific user action. This is achieved through the context.Database property.1 + +### **Programmatic Migration with Migrate()** + +Applications can programmatically apply pending migrations by calling context.Database.Migrate() or MigrateAsync().8 If a migration contains the file-reading logic described previously, this call will effectively execute the INSERT and UPDATE statements from the .sql file.9 While convenient for local testing and small-scale deployments, this approach is often discouraged for production environments due to potential race conditions in multi-instance deployments and the elevated database permissions required by the application.8 + +### **Direct Script Execution** + +For ad-hoc script application, developers can use ExecuteSqlRawAsync directly within a service or controller. This is particularly useful for maintenance tasks or high-performance data patching that does not belong in the schema version history.14 + +C\# + +// Example of direct execution logic within a service +public async Task ApplyPatchAsync(string fileName) +{ + var sql \= await File.ReadAllTextAsync(Path.Combine(\_basePath, fileName)); + using (var context \= \_contextFactory.CreateDbContext()) + { + await context.Database.ExecuteSqlRawAsync(sql); + } +} + +1 + +## **The Performance Frontier: Benchmarking Bulk Data Operations** + +The decision to use raw SQL scripts for INSERT and UPDATE operations is frequently driven by performance considerations. The traditional EF Core pattern of row-by-row updates is fundamentally limited by the latency of individual database round-trips and the computational cost of change tracking.6 + +### **Quantitative Impact of Bulk Operations** + +When processing large datasets, the performance gains of raw SQL are significant. Research suggests that for an operation involving 5,000 records, the standard SaveChanges() method may take approximately 85 seconds, whereas a bulk operation can complete the same task in approximately 1 second.6 This represents a 98.8% reduction in execution time.6 + +The efficiency can be quantified using the following relationship: + +$$\\text{Speedup Factor} \= \\frac{\\text{Time}\_{\\text{Tracked}}}{\\text{Time}\_{\\text{Bulk}}}$$ + +In high-latency environments, where the time per round-trip is a major bottleneck, the speedup factor for raw SQL bulk operations can exceed 85x for inserts and 10x-30x for updates and deletes.6 + +| Operation Type | Rows | SaveChanges Time | Bulk/SQL Time | Efficiency Improvement | +| :---- | :---- | :---- | :---- | :---- | +| **Insert** | 5,000 | 85.0s | 1.0s | 85.0x | +| **Insert** | 100,000 | 595.0s | 7.0s | 85.0x | +| **Insert** | 1,000,000 | 17,000s | 25.0s | 680.0x | +| **Update** | 1,000 | 17.0s | 0.5s | 34.0x | + +6 + +These gains are primarily attributed to the reduction of database round-trips. While SaveChanges() sends $N$ statements for $N$ records, a raw SQL script or an ExecuteUpdate call typically sends a single statement that the database engine can optimize internally.5 Furthermore, the memory footprint is dramatically reduced because EF Core does not need to instantiate or track entity objects, which can consume up to 2GB of memory for a million-record operation.6 + +## **Architectural Deployment: From Development to Production** + +Deploying database changes that include raw SQL files requires a strategy that balances developer productivity with production safety. The EF Core documentation highlights several distinct strategies for applying migrations.8 + +### **Recommended Production Pattern: SQL Scripts** + +For production environments, the most recommended strategy is the generation of SQL scripts using dotnet ef migrations script.8 This allows a Database Administrator (DBA) to review the generated SQL—including the contents of any INSERT or UPDATE statements pulled from .sql files—before they are executed.2 This "script-first" deployment model provides the highest level of control and minimizes the risk of accidental data loss.2 + +### **Idempotent Deployment** + +In environments where the current state of the database may be unknown, idempotent scripts are invaluable. By using the \--idempotent flag with the script generation command, EF Core produces a script that checks the \_\_EFMigrationsHistory table before executing each migration block.8 This ensures that the same script can be run multiple times without causing errors or duplicate data entries, as the script will only apply those migrations that are currently missing.2 + +### **Migration Bundles (efbundle)** + +For modern DevOps pipelines, Migration Bundles provide a self-contained, single-file executable (efbundle.exe) that can apply migrations to a target database.8 Bundles are advantageous because they do not require the.NET SDK or the project source code to be present on the production server.8 When a migration includes logic to read a .sql file, that file must be available in the execution directory of the bundle, or it must have been embedded into the assembly at build time.8 + +## **Security and Data Integrity in the Raw SQL Lifecycle** + +Executing raw SQL statements from external files introduces specific security and integrity concerns that must be addressed through architectural safeguards. + +### **SQL Injection Prevention** + +The primary security risk associated with raw SQL is SQL injection. While static .sql files are generally safe if their content is controlled by the development team, any logic that dynamicallly alters the script before execution must be carefully scrutinized.1 Developers should avoid concatenating user input into SQL strings. When using ExecuteSqlRaw, parameterization should be used for variable values.1 + +C\# + +// Secure parameterization example +var category \= "Electronics"; +var increase \= 1.10; +context.Database.ExecuteSqlRaw( + "UPDATE Products SET Price \= Price \* {0} WHERE Category \= {1}", + increase, category); + +1 + +### **The ChangeTracker Disconnect** + +A critical implication of using raw SQL for UPDATE and INSERT operations is that these commands bypass the EF Core Change Tracker.5 If an application executes an UPDATE statement via raw SQL that modifies a record already loaded into memory, the in-memory entity will become "stale," reflecting the old data state.7 This can lead to data inconsistency if the stale entity is later modified and saved via SaveChanges.7 + +To maintain consistency, developers should: + +1. **Execute bulk operations before loading data:** Ensure the database is in the desired state before entities are fetched for processing.5 +2. **Clear the Change Tracker:** If data has already been loaded, calling context.ChangeTracker.Clear() ensures that subsequent queries fetch the updated values from the database.7 +3. **Use Transactions:** Wrapping both raw SQL execution and subsequent EF Core operations in a common transaction ensures that either all changes are committed or none are, preventing partial state updates in the event of an error.7 + +## **Advanced Extensibility and Custom Operations** + +For organizations that frequently utilize SQL scripts, the EF Core migration pipeline can be extended to support specialized operations. This is achieved by subclassing MigrationOperation and providing a custom IMigrationsSqlGenerator.27 + +### **Creating a SqlFileOperation** + +Rather than manually reading file contents in every migration, a developer can define a SqlFileOperation that takes a filename as a parameter.27 A custom SQL generator then intercepts this operation and handles the provider-specific logic for executing the file's contents.27 This approach allows for cleaner migration code and centralizes the logic for file handling and security validation.27 + +C\# + +// Architectural pattern for a custom migration operation +public class CreateStoredProcedureOperation : MigrationOperation +{ + public string Name { get; set; } + public string ScriptPath { get; set; } +} + +public static class MigrationBuilderExtensions +{ + public static OperationBuilder\ CreateStoredProcedure( + this MigrationBuilder builder, string name, string path) + { + var op \= new CreateStoredProcedureOperation { Name \= name, ScriptPath \= path }; + builder.Operations.Add(op); + return new OperationBuilder\(op); + } +} + +20 + +This level of extensibility allows teams to create a domain-specific language (DSL) for their database changes, incorporating scripts for custom permissions, auditing triggers, or complex reporting views while still benefiting from the dotnet ef CLI's management capabilities.27 + +## **The Impact of Modern Framework Evolution (EF Core 9 & 10\)** + +The release of EF Core 9.0 and the upcoming EF Core 10 introduce several breaking changes and enhancements that affect how raw SQL is managed and executed. + +### **Enforced Model Consistency** + +Starting with EF Core 9.0, the framework introduces a stricter check for model consistency. If the tools detect pending model changes that have not been captured in a migration, an exception is thrown when calling database update or Migrate().26 This ensures that developers do not accidentally bypass the migration history when making schema changes.26 For developers using raw SQL files to manage objects that EF Core is unaware of (such as custom roles or permissions), it is necessary to use annotations to ensure EF Core tracks these changes as part of the model.28 + +### **Transaction Strategy Changes** + +Another significant change in EF Core 9.0 is the default transaction behavior for migrations. Calls to Migrate() and MigrateAsync() now automatically start a transaction and execute commands using an execution strategy.26 This improvement ensures higher reliability for multi-step migrations but may require developers to adjust their code if they were previously managing transactions manually.26 + +### **Enhancements in Bulk Updates** + +EF Core 9 and 10 continue to improve the ExecuteUpdate and ExecuteDelete APIs. EF Core 9 added support for complex type properties in bulk updates, and EF Core 10 is slated to allow regular lambdas (rather than just expression trees) for ExecuteUpdateAsync, making dynamic and conditional updates significantly easier to write in C\#.5 As these LINQ-based bulk operations become more powerful, the necessity of falling back to raw SQL files may decrease for standard data transformations, though scripts will remain the primary choice for complex, pre-tuned database logic.5 + +## **Navigating the Hybrid Persistence Model** + +The effective application of INSERT and UPDATE statements from .sql files using dotnet ef requires a nuanced understanding of the framework's internal mechanisms and the broader database deployment lifecycle. While raw SQL offers unparalleled performance and access to provider-specific features, it must be used within the structured confines of the migrations system to maintain the integrity and maintainability of the application. + +By leveraging embedded resources for script storage, utilizing idempotent deployment strategies for production, and remaining mindful of the Change Tracker's disconnect during raw SQL execution, engineering teams can build highly performant and reliable data layers. As Entity Framework Core continues to evolve, the distinction between high-level ORM operations and low-level SQL execution is becoming increasingly blurred, allowing for a hybrid model where developers can choose the most efficient tool for any given task without sacrificing the benefits of a managed, version-controlled environment. + +The quantitative evidence for the efficiency of bulk operations highlights the necessity of this hybrid approach. In an era of massive datasets and high-concurrency cloud applications, the ability to bypass row-by-row processing in favor of set-based SQL execution is a critical performance tier that every professional developer must be prepared to implement. Whether through the direct use of CLI tools or the programmatic orchestration of migrations, the integration of raw SQL files remains a cornerstone of professional.NET database development. + +#### **Works cited** + +1.

While dotnet ef is primarily designed for C\#-based migrations, it provides hooks to execute raw SQL. + +## **1\. The Migration Strategy (Recommended)** + +The most robust way to apply SQL files is through EF Core Migrations. This ensures that the SQL script is versioned along with your schema and executed automatically across environments. + +### **Step-by-Step Workflow** + +1. Create an Empty Migration: + Run the following command in your terminal: + dotnet ef migrations add SeedDataFromSql + +2. Embed the SQL File: + To ensure the .sql file is accessible when the application is compiled or deployed, add it to your .csproj as an Embedded Resource: + \ + \ + \ + +3. Read and Execute in the Migration: + Inside the generated migration's Up method, use MigrationBuilder.Sql() to execute the contents of the file. + +## **2\. The Raw Execution Strategy** + +If you need to run a script ad-hoc without a migration (for example, in a CI/CD pipeline or a startup routine), you can use the DbContext.Database.ExecuteSqlRaw method. + +### **Implementation Example:** + +var sql \= File.ReadAllText("path/to/script.sql"); +using (var context \= new MyDbContext()) +{ + context.Database.ExecuteSqlRaw(sql); +} + +## **3\. Tooling and CLI Alternatives** + +### **SQL Idempotency** + +When using dotnet ef migrations script, you can generate a full SQL script representing your migrations. If your .sql file is already integrated into a migration, it will be included in this output. + +dotnet ef migrations script \--output bundle.sql \--idempotent + +### **EF Core Power Tools** + +For developers who prefer a UI, **EF Core Power Tools** (a Visual Studio extension) allows for easier management of SQL-based migrations and schema comparisons. + +## **4\. Key Considerations** + +| Feature | Description | +| :---- | :---- | +| **Transaction Management** | EF Migrations wrap your SQL in a transaction by default. If your script contains COMMIT or ROLLBACK, it may cause errors. | +| **Provider Specificity** | Raw SQL is often specific to a provider (e.g., T-SQL for SQL Server vs. PL/pgSQL for PostgreSQL). Ensure your script matches your target DB. | +| **Execution Order** | When using migrations, the INSERT and UPDATE statements will always run after the schema changes defined in the same migration. | +| **Pathing** | Use AppDomain.CurrentDomain.BaseDirectory or Embedded Resources to avoid "file not found" errors in production environments. | + +## **Conclusion** + +The best practice is to incorporate .sql files into **EF Core Migrations** using migrationBuilder.Sql(). This maintains a single source of truth for your database state and leverages the existing dotnet ef database update workflow. \ No newline at end of file diff --git a/SESSION_SUMMARY.md b/SESSION_SUMMARY.md index b2b10fd..efa723a 100644 --- a/SESSION_SUMMARY.md +++ b/SESSION_SUMMARY.md @@ -35,6 +35,8 @@ **Database State / Migrations:** - Migration `AddCatalogSchema` creates `Categories` table and adds `CategoryId`, `CreatedAt`, `Description` to `Products`. - Apply with: `make migrate` (requires SQL Server running via `make db-start`). +- `sample-seed.sql` provides example rows for the default schema;

[DONE] +- IMPLEMENTATION DETAILS: Created EntitiesController.cs with reflection-based approach since EF Core 8 lacks non-generic Set(Type) method. + Uses reflection to call generic Set(), ToListAsync(), and CountAsync() with runtime types. 3) Add generic API client for entities - Create `IEntityApiService` with `GetEntitiesAsync(entityName)` and `GetCountAsync(entityName)`. diff --git a/tests/DotNetWebApp.Tests/EntitiesControllerTests.cs b/tests/DotNetWebApp.Tests/EntitiesControllerTests.cs new file mode 100644 index 0000000..e08e437 --- /dev/null +++ b/tests/DotNetWebApp.Tests/EntitiesControllerTests.cs @@ -0,0 +1,272 @@ +using System.Collections.Generic;

While Entity Framework Core is fundamentally architected to facilitate database interactions through Language Integrated Query and a declarative model-building paradigm, modern enterprise applications frequently encounter operational requirements that necessitate direct SQL execution. These requirements often include the orchestration of complex data migrations, the deployment of provider-specific database objects such as stored procedures, triggers, or views, and the execution of high-volume bulk operations that surpass the efficiency of the standard Change Tracker mechanism.1 The ability to apply INSERT and UPDATE statements from external .sql files using the dotnet ef command-line interface is not merely a technical utility but a critical component of a robust database deployment strategy. - -## **The Paradigm of Managed Persistence and the Role of Raw SQL** - -Entity Framework Core serves as a bridge between the imperative world of C\# and the relational world of SQL. However, the framework's design acknowledges that LINQ cannot express every possible database operation with optimal efficiency.1 In early iterations of the framework, performing bulk updates required developers to load entire datasets into memory, modify the entities individually, and then call SaveChanges, a process that incurred massive overhead in terms of both memory allocation and network latency.1 Although EF Core 7.0 and subsequent versions introduced the ExecuteUpdate and ExecuteDelete methods to provide a more efficient LINQ-to-SQL translation for set-based operations, many legacy systems and complex data-seeding tasks still rely on pre-existing SQL scripts that have been manually tuned for performance.1 - -The dotnet ef toolset provides the necessary infrastructure to manage these scripts within the application’s lifecycle. By utilizing the migrations pipeline, developers can ensure that INSERT and UPDATE operations contained within .sql files are executed in a versioned, repeatable manner across different environments, from local development to production.3 This managed approach to raw SQL execution mitigates the risks associated with manual database patching and ensures that the database schema and its underlying data remain synchronized with the application code.2 - -## **The dotnet ef CLI Infrastructure** - -The dotnet ef command-line interface is an extension of the.NET CLI that enables design-time tasks such as migration generation, database updates, and model scaffolding.11 To utilize these tools, developers must install the dotnet-ef tool globally or locally and include the Microsoft.EntityFrameworkCore.Design package in their target project.11 The CLI acts as the primary orchestrator for applying migrations that may contain raw SQL logic. - -### **Core Commands for Script Management** - -The lifecycle of a database change involving a .sql file typically begins with the generation of a migration. The CLI offers several commands that are instrumental in this process. - -| Command | Functionality | Context for SQL Files | -| :---- | :---- | :---- | -| dotnet ef migrations add | Scaffolds a new migration file based on model changes. | Creates the Up and Down methods where file-reading logic is placed. | -| dotnet ef database update | Applies pending migrations to the target database. | Triggers the execution of the SQL contained in the referenced files. | -| dotnet ef migrations script | Generates a SQL script from a range of migrations. | Embeds the content of the .sql files into a larger deployment script. | -| dotnet ef migrations bundle | Creates a self-contained executable for applying migrations. | Packages the file-reading logic and SQL scripts for CI/CD pipelines. | -| dotnet ef dbcontext info | Provides metadata about the current DbContext. | Useful for verifying the connection string and provider before execution. | - -8 - -A critical distinction must be made between the "Target Project" and the "Startup Project" when executing these commands. The target project is where the migrations and model files reside, while the startup project is the entry point that the tools build and run to access the DbContext configuration, including connection strings and database providers.11 If the DbContext is located in a class library, a separate console application or web project must serve as the startup project to provide the necessary runtime environment for the tools.11 - -## **Mechanisms of Raw SQL Execution: A Taxonomy** - -To apply INSERT and UPDATE statements from a file, the content of that file must eventually be passed to one of EF Core’s raw SQL execution APIs. The framework provides several methods for this purpose, each with distinct behaviors regarding entity tracking and return values. - -### **The ExecuteSql and ExecuteSqlRaw APIs** - -The Database property of the DbContext exposes the ExecuteSql and ExecuteSqlRaw methods, which are designed specifically for DDL (Data Definition Language) and DML (Data Manipulation Language) operations that do not return entity results.1 When a SQL file containing multiple INSERT or UPDATE statements is read into a string, it can be passed to these methods. ExecuteSqlRaw returns an integer representing the total number of rows affected by the command.1 - -A notable evolutionary step occurred in EF Core 7.0, where ExecuteSql was introduced as a more modern alternative to ExecuteSqlRaw, supporting string interpolation for easier parameterization while maintaining protection against SQL injection.1 However, for executing the static content of a file where parameters are not dynamically injected, ExecuteSqlRaw remains the standard choice.14 - -### **FromSql and Query-Based Execution** - -While ExecuteSql is used for commands that modify state, FromSql (and its predecessor FromSqlRaw) is used to begin a LINQ query based on a SQL statement.4 While primarily used for SELECT queries, FromSql can be used to execute stored procedures that might perform updates while also returning data.4 However, it is important to note that FromSql can only be used on a DbSet and requires the SQL query to return data for all properties of the mapped entity type.4 - -## **Strategic Implementation of SQL File Integration in Migrations** - -The most common and recommended approach for applying SQL statements from a file is to integrate the execution logic directly into an EF Core migration. This ensures that the data operations are performed at the correct point in the database's version history.2 - -### **The Migration Lifecycle** - -When the dotnet ef migrations add command is executed, EF Core compares the current model with the previous model snapshot to identify changes.9 To include a custom SQL file, a developer can generate an empty migration by making no model changes and then manually editing the generated file.10 The Up method of the migration class should be modified to include a call to migrationBuilder.Sql(), which accepts a string containing the SQL to be executed.18 - -### **File Access Methodologies in C\#** - -Reading a .sql file during a migration requires careful consideration of file paths and deployment environments. Because migrations are executed both in development (via the CLI) and in production (potentially via bundles or runtime calls), the method of locating the file must be robust. - -One common approach is to use relative paths from the project's base directory. However, Directory.GetCurrentDirectory() can be unreliable when the CLI is invoked from different folders.16 A more stable alternative is to use AppDomain.CurrentDomain.BaseDirectory or AppContext.BaseDirectory, which points to the location of the compiled assemblies.16 - -For maximum reliability in distributed systems, the SQL files should be treated as "Embedded Resources".16 By setting the build action to embedded, the script content is compiled directly into the assembly, eliminating the risk of a "file not found" exception during a remote deployment.16 The migration then uses the Assembly class to retrieve the resource stream and read its contents into a string for the migrationBuilder.Sql() method.16 - -| File Access Method | Implementation Detail | Pros | Cons | -| :---- | :---- | :---- | :---- | -| **Physical File (Relative)** | File.ReadAllText("Scripts/data.sql") | Simple to edit during development. | Path may break in different environments. | -| **Physical File (Absolute)** | Path.Combine(AppContext.BaseDirectory,...) | More stable than relative paths. | Still relies on external file presence. | -| **Embedded Resource** | GetManifestResourceStream() | Extremely portable; no external file dependencies. | Requires project rebuild to update script. | -| **Project Resource** | Resources.MyScript | Easy access via strongly-typed properties. | Embeds SQL in assembly metadata; may increase binary size. | - -16 - -## **Runtime Orchestration: Applying SQL via DbContext** - -In some scenarios, it is necessary to apply SQL scripts outside of the migration pipeline, such as during application startup or in response to a specific user action. This is achieved through the context.Database property.1 - -### **Programmatic Migration with Migrate()** - -Applications can programmatically apply pending migrations by calling context.Database.Migrate() or MigrateAsync().8 If a migration contains the file-reading logic described previously, this call will effectively execute the INSERT and UPDATE statements from the .sql file.9 While convenient for local testing and small-scale deployments, this approach is often discouraged for production environments due to potential race conditions in multi-instance deployments and the elevated database permissions required by the application.8 - -### **Direct Script Execution** - -For ad-hoc script application, developers can use ExecuteSqlRawAsync directly within a service or controller. This is particularly useful for maintenance tasks or high-performance data patching that does not belong in the schema version history.14 - -C\# - -// Example of direct execution logic within a service -public async Task ApplyPatchAsync(string fileName) -{ - var sql \= await File.ReadAllTextAsync(Path.Combine(\_basePath, fileName)); - using (var context \= \_contextFactory.CreateDbContext()) - { - await context.Database.ExecuteSqlRawAsync(sql); - } -} - -1 - -## **The Performance Frontier: Benchmarking Bulk Data Operations** - -The decision to use raw SQL scripts for INSERT and UPDATE operations is frequently driven by performance considerations. The traditional EF Core pattern of row-by-row updates is fundamentally limited by the latency of individual database round-trips and the computational cost of change tracking.6 - -### **Quantitative Impact of Bulk Operations** - -When processing large datasets, the performance gains of raw SQL are significant. Research suggests that for an operation involving 5,000 records, the standard SaveChanges() method may take approximately 85 seconds, whereas a bulk operation can complete the same task in approximately 1 second.6 This represents a 98.8% reduction in execution time.6 - -The efficiency can be quantified using the following relationship: - -$$\\text{Speedup Factor} \= \\frac{\\text{Time}\_{\\text{Tracked}}}{\\text{Time}\_{\\text{Bulk}}}$$ - -In high-latency environments, where the time per round-trip is a major bottleneck, the speedup factor for raw SQL bulk operations can exceed 85x for inserts and 10x-30x for updates and deletes.6 - -| Operation Type | Rows | SaveChanges Time | Bulk/SQL Time | Efficiency Improvement | -| :---- | :---- | :---- | :---- | :---- | -| **Insert** | 5,000 | 85.0s | 1.0s | 85.0x | -| **Insert** | 100,000 | 595.0s | 7.0s | 85.0x | -| **Insert** | 1,000,000 | 17,000s | 25.0s | 680.0x | -| **Update** | 1,000 | 17.0s | 0.5s | 34.0x | - -6 - -These gains are primarily attributed to the reduction of database round-trips. While SaveChanges() sends $N$ statements for $N$ records, a raw SQL script or an ExecuteUpdate call typically sends a single statement that the database engine can optimize internally.5 Furthermore, the memory footprint is dramatically reduced because EF Core does not need to instantiate or track entity objects, which can consume up to 2GB of memory for a million-record operation.6 - -## **Architectural Deployment: From Development to Production** - -Deploying database changes that include raw SQL files requires a strategy that balances developer productivity with production safety. The EF Core documentation highlights several distinct strategies for applying migrations.8 - -### **Recommended Production Pattern: SQL Scripts** - -For production environments, the most recommended strategy is the generation of SQL scripts using dotnet ef migrations script.8 This allows a Database Administrator (DBA) to review the generated SQL—including the contents of any INSERT or UPDATE statements pulled from .sql files—before they are executed.2 This "script-first" deployment model provides the highest level of control and minimizes the risk of accidental data loss.2 - -### **Idempotent Deployment** - -In environments where the current state of the database may be unknown, idempotent scripts are invaluable. By using the \--idempotent flag with the script generation command, EF Core produces a script that checks the \_\_EFMigrationsHistory table before executing each migration block.8 This ensures that the same script can be run multiple times without causing errors or duplicate data entries, as the script will only apply those migrations that are currently missing.2 - -### **Migration Bundles (efbundle)** - -For modern DevOps pipelines, Migration Bundles provide a self-contained, single-file executable (efbundle.exe) that can apply migrations to a target database.8 Bundles are advantageous because they do not require the.NET SDK or the project source code to be present on the production server.8 When a migration includes logic to read a .sql file, that file must be available in the execution directory of the bundle, or it must have been embedded into the assembly at build time.8 - -## **Security and Data Integrity in the Raw SQL Lifecycle** - -Executing raw SQL statements from external files introduces specific security and integrity concerns that must be addressed through architectural safeguards. - -### **SQL Injection Prevention** - -The primary security risk associated with raw SQL is SQL injection. While static .sql files are generally safe if their content is controlled by the development team, any logic that dynamicallly alters the script before execution must be carefully scrutinized.1 Developers should avoid concatenating user input into SQL strings. When using ExecuteSqlRaw, parameterization should be used for variable values.1 - -C\# - -// Secure parameterization example -var category \= "Electronics"; -var increase \= 1.10; -context.Database.ExecuteSqlRaw( - "UPDATE Products SET Price \= Price \* {0} WHERE Category \= {1}", - increase, category); - -1 - -### **The ChangeTracker Disconnect** - -A critical implication of using raw SQL for UPDATE and INSERT operations is that these commands bypass the EF Core Change Tracker.5 If an application executes an UPDATE statement via raw SQL that modifies a record already loaded into memory, the in-memory entity will become "stale," reflecting the old data state.7 This can lead to data inconsistency if the stale entity is later modified and saved via SaveChanges.7 - -To maintain consistency, developers should: - -1. **Execute bulk operations before loading data:** Ensure the database is in the desired state before entities are fetched for processing.5 -2. **Clear the Change Tracker:** If data has already been loaded, calling context.ChangeTracker.Clear() ensures that subsequent queries fetch the updated values from the database.7 -3. **Use Transactions:** Wrapping both raw SQL execution and subsequent EF Core operations in a common transaction ensures that either all changes are committed or none are, preventing partial state updates in the event of an error.7 - -## **Advanced Extensibility and Custom Operations** - -For organizations that frequently utilize SQL scripts, the EF Core migration pipeline can be extended to support specialized operations. This is achieved by subclassing MigrationOperation and providing a custom IMigrationsSqlGenerator.27 - -### **Creating a SqlFileOperation** - -Rather than manually reading file contents in every migration, a developer can define a SqlFileOperation that takes a filename as a parameter.27 A custom SQL generator then intercepts this operation and handles the provider-specific logic for executing the file's contents.27 This approach allows for cleaner migration code and centralizes the logic for file handling and security validation.27 - -C\# - -// Architectural pattern for a custom migration operation -public class CreateStoredProcedureOperation : MigrationOperation -{ - public string Name { get; set; } - public string ScriptPath { get; set; } -} - -public static class MigrationBuilderExtensions -{ - public static OperationBuilder\ CreateStoredProcedure( - this MigrationBuilder builder, string name, string path) - { - var op \= new CreateStoredProcedureOperation { Name \= name, ScriptPath \= path }; - builder.Operations.Add(op); - return new OperationBuilder\(op); - } -} - -20 - -This level of extensibility allows teams to create a domain-specific language (DSL) for their database changes, incorporating scripts for custom permissions, auditing triggers, or complex reporting views while still benefiting from the dotnet ef CLI's management capabilities.27 - -## **The Impact of Modern Framework Evolution (EF Core 9 & 10\)** - -The release of EF Core 9.0 and the upcoming EF Core 10 introduce several breaking changes and enhancements that affect how raw SQL is managed and executed. - -### **Enforced Model Consistency** - -Starting with EF Core 9.0, the framework introduces a stricter check for model consistency. If the tools detect pending model changes that have not been captured in a migration, an exception is thrown when calling database update or Migrate().26 This ensures that developers do not accidentally bypass the migration history when making schema changes.26 For developers using raw SQL files to manage objects that EF Core is unaware of (such as custom roles or permissions), it is necessary to use annotations to ensure EF Core tracks these changes as part of the model.28 - -### **Transaction Strategy Changes** - -Another significant change in EF Core 9.0 is the default transaction behavior for migrations. Calls to Migrate() and MigrateAsync() now automatically start a transaction and execute commands using an execution strategy.26 This improvement ensures higher reliability for multi-step migrations but may require developers to adjust their code if they were previously managing transactions manually.26 - -### **Enhancements in Bulk Updates** - -EF Core 9 and 10 continue to improve the ExecuteUpdate and ExecuteDelete APIs. EF Core 9 added support for complex type properties in bulk updates, and EF Core 10 is slated to allow regular lambdas (rather than just expression trees) for ExecuteUpdateAsync, making dynamic and conditional updates significantly easier to write in C\#.5 As these LINQ-based bulk operations become more powerful, the necessity of falling back to raw SQL files may decrease for standard data transformations, though scripts will remain the primary choice for complex, pre-tuned database logic.5 - -## **Navigating the Hybrid Persistence Model** - -The effective application of INSERT and UPDATE statements from .sql files using dotnet ef requires a nuanced understanding of the framework's internal mechanisms and the broader database deployment lifecycle. While raw SQL offers unparalleled performance and access to provider-specific features, it must be used within the structured confines of the migrations system to maintain the integrity and maintainability of the application. - -By leveraging embedded resources for script storage, utilizing idempotent deployment strategies for production, and remaining mindful of the Change Tracker's disconnect during raw SQL execution, engineering teams can build highly performant and reliable data layers. As Entity Framework Core continues to evolve, the distinction between high-level ORM operations and low-level SQL execution is becoming increasingly blurred, allowing for a hybrid model where developers can choose the most efficient tool for any given task without sacrificing the benefits of a managed, version-controlled environment. - -The quantitative evidence for the efficiency of bulk operations highlights the necessity of this hybrid approach. In an era of massive datasets and high-concurrency cloud applications, the ability to bypass row-by-row processing in favor of set-based SQL execution is a critical performance tier that every professional developer must be prepared to implement. Whether through the direct use of CLI tools or the programmatic orchestration of migrations, the integration of raw SQL files remains a cornerstone of professional.NET database development. - -#### **Works cited** - -1.

Ensure your script matches your target DB. | -| **Execution Order** | When using migrations, the INSERT and UPDATE statements will always run after the schema changes defined in the same migration. | -| **Pathing** | Use AppDomain.CurrentDomain.BaseDirectory or Embedded Resources to avoid "file not found" errors in production environments. | - -## **Conclusion** - -The best practice is to incorporate .sql files into **EF Core Migrations** using migrationBuilder.Sql(). This maintains a single source of truth for your database state and leverages the existing dotnet ef database update workflow. \ No newline at end of file diff --git a/TASK2_REVIEW.md b/TASK2_REVIEW.md deleted file mode 100644 index 28d93d7..0000000 --- a/TASK2_REVIEW.md +++ /dev/null @@ -1,324 +0,0 @@ -# Task #2 Implementation Review: Dynamic API Endpoints - -**Date:** 2026-01-22 -**Status:** ✅ Ready for Commit -**Branch:** templify - ---- - -## Summary - -Implemented dynamic API endpoints at `api/entities/{entityName}` that work with any entity defined in app.yaml.

This task is blocked by TODO #1. + +**Problem:** EntitiesController contains 50+ lines of reflection logic that should be encapsulated. + +**Files affected:** +- `/Controllers/EntitiesController.cs` (lines 37-87, 89-115, 117-143) + +**Solution:** Create `IEntityOperationService` + +```csharp +// New file: /Services/IEntityOperationService.cs +public interface IEntityOperationService +{ + Task GetAllAsync(Type entityType, CancellationToken ct = default); + Task GetCountAsync(Type entityType, CancellationToken ct = default); + Task CreateAsync(Type entityType, object entity, CancellationToken ct = default); + Task GetByIdAsync(Type entityType, object id, CancellationToken ct = default); + Task UpdateAsync(Type entityType, object entity, CancellationToken ct = default); + Task DeleteAsync(Type entityType, object id, CancellationToken ct = default); +} +``` + +**Benefit:** Reduces EntitiesController from ~200 lines to ~80 lines; centralizes reflection logic for reuse and testing. + +#### 2. Add Input Validation Pipeline + +**Problem:** Controllers deserialize JSON without schema validation. + +**Files affected:** +- `/Controllers/EntitiesController.cs` (CreateEntity, UpdateEntity methods) +- `/Controllers/GenericController.cs` (Post method) + +**Solution:** Add FluentValidation or Data Annotations validation middleware + +```csharp +[HttpPost("{entityName}")] +public async Task CreateEntity(string entityName) +{ + var metadata = _metadataService.Find(entityName); + var entity = JsonSerializer.Deserialize(json, metadata.ClrType); + + // NEW: Validate before saving + var validationResults = new List(); + var context = new ValidationContext(entity); + if (!Validator.TryValidateObject(entity, context, validationResults, validateAllProperties: true)) + { + return BadRequest(new { errors = validationResults.Select(v => v.ErrorMessage) }); + } + + await _operationService.CreateAsync(metadata.ClrType, entity); + return CreatedAtAction(nameof(GetEntities), new { entityName }, entity); +} +``` + +**Benefit:** Prevents invalid data from reaching the database; respects [Required], [MaxLength], etc. attributes on generated models. + +#### 3. Migrate to Finbuckle.MultiTenant + +**Problem:** Custom multi-tenant implementation lacks advanced features and maintenance support. + +**Files to replace/modify:** +- DELETE: `/Data/Tenancy/ITenantSchemaAccessor.cs` +- DELETE: `/Data/Tenancy/HeaderTenantSchemaAccessor.cs` +- DELETE: `/Data/Tenancy/TenantSchemaOptions.cs` +- MODIFY: `/Data/AppDbContext.cs` (use Finbuckle's ITenantInfo) +- MODIFY: `Program.cs` (register Finbuckle services) + +**Implementation steps:** +1. Install NuGet package: `Finbuckle.MultiTenant.AspNetCore` v8.x +2. Configure tenant resolution strategy (header-based) +3. Implement `ITenantInfo` with Schema property +4. Update AppDbContext to use `MultiTenantDbContext` +5. Remove custom tenant accessor classes + +**Benefit:** Robust tenant resolution, better data isolation patterns, active community support. + +### MEDIUM PRIORITY + +#### 4. Implement Repository Pattern + +**Problem:** Controllers tightly coupled to EF Core DbContext. + +**Files affected:** +- `/Controllers/EntitiesController.cs` +- `/Controllers/GenericController.cs` +- New files: `/Repositories/IRepository.cs`, `/Repositories/GenericRepository.cs` + +**Solution:** Create generic repository abstraction + +```csharp +public interface IRepository where TEntity : class +{ + Task> GetAllAsync(CancellationToken ct = default); + Task GetByIdAsync(object id, CancellationToken ct = default); + Task CreateAsync(TEntity entity, CancellationToken ct = default); + Task UpdateAsync(TEntity entity, CancellationToken ct = default); + Task DeleteAsync(object id, CancellationToken ct = default); + Task CountAsync(CancellationToken ct = default); +} +``` + +**Benefit:** Decouples from EF Core, easier to test with mocks, enables future ORM flexibility. + +#### 5. Make YAML Models Immutable + +**Problem:** AppDefinition, Entity, Property classes use mutable properties. + +**Files affected:** +- `/Models/AppDictionary/AppDefinition.cs` +- `/Models/AppDictionary/Entity.cs` +- `/Models/AppDictionary/Property.cs` +- `/Models/AppDictionary/Relationship.cs` +- `/Models/AppDictionary/AppMetadata.cs` +- `/Models/AppDictionary/Theme.cs` + +**Solution:** Change all `set` accessors to `init` + +```csharp +public class AppDefinition +{ + public AppMetadata App { get; init; } = null!; + public Theme Theme { get; init; } = null!; + public DataModel DataModel { get; init; } = null!; +} +``` + +**Benefit:** Prevents accidental mutation after deserialization; better thread safety; clearer intent. + +#### 6. Consolidate Configuration Sources + +**AUDIT COMPLETE:** See TODO.txt #4 for configuration consolidation audit findings. + +**Summary:** +- ✅ TenantSchemaOptions: Already properly configured (defaults overridden by appsettings.json) +- ✅ DdlParser YamlGenerator: Defaults are appropriate for code generation tool +- ❌ DataSeeder.SeedFileName: NEEDS FIX - move from const to appsettings.json configuration + +**Problem:** Configuration scattered across appsettings.json, app.yaml, and hard-coded constants. + +**Files affected:** +- `appsettings.json` +- `/Data/DataSeeder.cs` (hard-coded "seed.sql") - **NEEDS CONFIGURATION EXTRACTION** +- `/Data/Tenancy/TenantSchemaOptions.cs` (hard-coded defaults) - **OK, no change needed** + +**Solution:** Move all hard-coded values to configuration + +```csharp +// appsettings.json +{ + "DataSeeder": { + "SeedFileName": "seed.sql" + }, + "TenantSchema": { + "DefaultSchema": "dbo", + "HeaderName": "X-Customer-Schema" + } +} +``` + +**Benefit:** Single source of configuration truth; easier environment-specific overrides. + +### NICE-TO-HAVE (Future Enhancements) + +#### 7. Add Dynamic Form Generation + +**Enhancement:** Add BlazorDynamicForm or MudBlazor.Forms for Create/Edit operations. + +**New files:** +- `/Components/Shared/DynamicEntityForm.razor` + +**Benefit:** Complete CRUD UI without manual form coding. + +#### 8. Expression-Based Queries + +**Enhancement:** Replace reflection with expression trees for better performance. + +**Files affected:** +- New file: `/Services/ExpressionHelpers.cs` +- `/Services/EntityOperationService.cs` + +**Benefit:** Better performance, compile-time type safety. + +#### 9. Support Multiple Database Providers + +**Enhancement:** Add PostgreSQL/MySQL support via multi-provider pattern. + +**Files affected:** +- `/DdlParser/` (add PostgreSQL/MySQL parsers) +- `/DdlParser/TypeMapper.cs` (database-specific type mappings) +- `Program.cs` (conditional DbContext registration) + +**Benefit:** Broader adoption, cloud flexibility. + +## Part 4: Critical Files for Refactoring + +### Tier 1 - Core Abstractions (Modify First) +1. `/Services/IEntityMetadataService.cs` - Metadata abstraction +2. `/Services/EntityMetadataService.cs` - Metadata implementation +3. `/Data/AppDbContext.cs` - Entity registration and tenant schema + +### Tier 2 - Controllers (Extract Logic) +4. `/Controllers/EntitiesController.cs` - Reflection-heavy dynamic API +5. ~~`/Controllers/GenericController.cs`~~ - **DELETED** (see TODO.txt #2 for architecture clarification) + +**NOTE:** Existing services (EntityApiService, DashboardService, SpaSectionService) do NOT require changes during refactoring.

EntitiesController = Dynamic pattern aligned with YAML-driven architecture - -**Decision Made:** -EntitiesController is the correct pattern because: -- ✅ Works with YAML-driven dynamic model discovery -- ✅ Supports unlimited entities without code generation -- ✅ Single endpoint handles all entities -- ✅ Aligns with DDL → YAML → Code → Dynamic API philosophy - -**Status:** GenericController has been deleted via git commit (already handled) - -**Impact on Refactoring:** -All REFACTOR.md recommendations focus on EntitiesController optimization. -No changes needed to GenericController architecture. - -3. Existing Service Layer Integration (VERIFIED - No code changes needed) - -**Finding:** -Three existing services work at DIFFERENT LAYERS and do NOT need modification: - -``` -Blazor Components (UI) - ↓ (calls via HTTP) -EntityApiService (HTTP client wrapper) - ↓ (calls endpoints) -EntitiesController (REST API layer) - ↓ (delegates to NEW service) -[PROPOSED] IEntityOperationService (reflection logic layer) - ↓ (accesses) -DbContext (data layer) -``` - -**Service Breakdown:** -- EntityApiService: HTTP client for Blazor → calls /api/entities/* endpoints - - Does NOT access DbContext directly - - Only calls REST endpoints (HTTP layer) - - Uses IEntityMetadataService for type information - -- DashboardService: Business logic that consumes EntityApiService - - Calls EntityApiService.GetCountAsync() to load dashboard data - - Used by Blazor dashboard components - - Works at business logic layer - -- SpaSectionService: UI navigation and routing - - Reads app.yaml via IAppDictionaryService - - Builds navigation menu from YAML definitions - - Completely independent from EntitiesController - -**Refactoring Impact: ZERO CODE CHANGES** - -When IEntityOperationService is extracted: -1. EntitiesController delegates reflection logic → IEntityOperationService ✅ -2. EntitiesController still exposes same HTTP endpoints ✅ -3. EntityApiService still calls same endpoints (no HTTP change) ✅ -4. DashboardService still calls EntityApiService (no change) ✅ -5. SpaSectionService continues unchanged ✅ - -**Why No Changes Needed:** -- Services work at different architectural layers -- They communicate through HTTP (for clients) or interfaces (for server) -- IEntityOperationService is an INTERNAL implementation detail -- External contracts (HTTP endpoints) remain identical - -**Status:** No action required. Services are properly decoupled. - -4.

prevents nested directory regression. -- `make test` runs all 5 tests (2 DotNetWebApp.Tests + 3 ModelGenerator.Tests) - all passing. -- `make dev` now scopes `dotnet watch` to `DotNetWebApp.csproj` to avoid building test projects during hot reload. - -**Database State / Migrations:** -- Database schema is generated from SQL DDL via `make run-ddl-pipeline`, which regenerates `app.yaml`, models, and a fresh migration in `Migrations/` (ignored in repo). -- Apply the generated migration with `make migrate` (requires SQL Server running via `make db-start`). -- `sample-seed.sql` provides example rows for the default schema; it now guards against duplicates and is executed by `SampleDataSeeder`. -- `make seed` invokes `dotnet run --project DotNetWebApp.csproj -- --seed`, which applies the generated migration via `Database.MigrateAsync()` and then executes `sample-seed.sql` via `ExecuteSqlRawAsync`; ensure the migration is generated from the DDL pipeline first. -- README documents how to install `mssql-tools` inside the SQL Server Docker container and how to query sample data after running `make seed`. - -**Tenant Schema:** Schema selection via `X-Customer-Schema` header (defaults to `dbo`). - -**Current Task Status:** ✅ **READY FOR NEXT PHASE** -- All core features implemented and tested (5/5 tests passing) -- DDL pipeline fully functional: `SQL → app.yaml → Models → Migration → Build` -- SPA sections are entity-driven and optional via `AppCustomization:EnableSpaExample` config -- Foundation complete: `IEntityMetadataService` maps app.yaml entities to CLR types for API/UI reuse -- See `CLAUDE.md` for detailed architecture, current features, and limitations -- See `README.md` for DDL parser usage and project structure -- See `TODO.txt` for incomplete actionable items - -**Next Steps (from TODO.txt):** -a) Explore dotnet aspnet codegenerator scaffolding for code generation -b) Break project reference cycle by extracting DotNetWebApp.Models to separate project -c) Add more SQL types to TypeMapper or refactor as needed for production MSSQL Server database +--- + +## Documentation Index + +This project is documented across multiple files.

+ +## Key Architectural Decisions + +### ✅ What We ARE Doing + +1. **Hybrid Data Access:** + - EF Core for all writes (200+ generated entities) + - Dapper for complex reads (SQL-first views) + - Shared connection for automatic tenant schema inheritance + +2. **SQL-First View Pipeline:** + - Legacy SQL queries as source of truth + - YAML registry (`views.yaml`) + - Generated C# view models + - Type-safe service layer (`IViewService`) + +3. **Multi-Tenancy:** + - Finbuckle.MultiTenant for robust tenant isolation + - Header-based strategy (`X-Customer-Schema`) + - Automatic schema propagation to Dapper (via shared EF connection) + +4. **Single-Project Organization:** + - Namespace-based separation (not 4 separate projects) + - Pragmatic for small team + - Can refactor to projects later if team grows + +5. **Dynamic Patterns:** + - Reflection-based entity operations (scalable to 200+ entities) + - Dynamic API endpoints (`/api/entities/{entityName}`) + - Runtime YAML-driven UI components + +### ❌ What We Are NOT Doing + +1. **Full Clean Architecture:** + - No Domain/Application/Infrastructure/WebUI projects + - Namespaces provide sufficient organization + +2. **Repository Pattern:** + - `IEntityOperationService` + `IViewService` are sufficient abstractions + - Avoids redundant layers + +3. **CQRS/Mediator:** + - Adds complexity without benefit at this scale + - Direct service calls are clearer + +4. **OData:** + - Our reflection-based approach is simpler + - More flexible for dynamic requirements + +5. **Client-Side Complexity:** + - No bloated JavaScript/AJAX + - Server-side C# event handlers via Blazor SignalR + +--- + +## Implementation Phases + +### ✅ Completed (Before 2026-01-26) + +- DDL-first entity generation pipeline +- Dynamic EF Core entity discovery +- Generic

See "Common Workflows" above. + +### Q: How do I add a new SQL view? + +**A:** Create SQL file, update `views.yaml`, run `make run-view-pipeline`. See "Common Workflows" above. + +### Q: Do I need to implement a repository for each entity? + +**A:** No! `IEntityOperationService` handles all 200+ entities dynamically via reflection. + +### Q: How does multi-tenancy work with Dapper? + +**A:** Dapper shares EF Core's connection, so tenant schema is automatic. No manual injection needed. + +### Q: Should I use Clean Architecture with separate projects? + +**A:** No. We use namespace-based organization in a single project.
