1.8.0

Windows App SDK 1.8.0 (1.8.250907003)

WinAppSDK 1.8.0 is the latest stable version of WinAppSDK providing new features and improvements to the platform.

Whats new in WinAppSDK 1.8.0:

  • The new Decimal support offers a high-precision base-10 numeric data type. It is structured as a 96-bit (12-byte) unsigned integer, scaled by a variable power of 10, allowing for precise representation of decimal values.
  • The Windows App SDK NuGet package has been converted to a NuGet metapackage. Each component contributing to the Windows App SDK is now a component NuGet package and is listed as a dependency by the metapackage. This allows developers to choose either the metapackage or select specific component packages for their applications.
  • The MSIX publishing support has been factored into a standalone nuget package, which can be independently maintained and consumed by Windows App SDK and other projects.
  • Prompt Size Limit Reporting allows applications to determine if an input exceeds the allowable size for a Text Summarizer call. If the input is too large, the API returns an index indicating the current limit, enabling developers to adjust the input accordingly.
  • Text Rewriter Tone enables text rewriting with specific tones. Choosing between Casual, Formal, and General options.
  • Phi Silica now has a Summarize Conversation feature that allows you to summarize what people have said over an email, chat, or thread.
  • Enables developers to specify the desired output language for conversation summarization. This allows applications to generate summaries in a targeted language, enhancing localization, and user experience.
  • Object Erase can be used to remove objects from images. The model takes both an image and a greyscale mask indicating the object to be removed, erases the masked area from the image, and replaces the erased area with the image background.
  • The Microsoft.Windows.Storage.Pickers API in the Windows App SDK provides a modernized file and folder picker experience for desktop applications. This API is based on the existing Windows.Storage.Pickers API design, but with key improvements for desktop scenarios.
  • Prior to WinAppSDK 1.8, packaged apps running in the AppContainer did not require the packageManagement capability, due to a DeploymentManager auto-initialization issue. That issue has now been resolved, and in turn, the packageManagement capability is now required for AppContainer-based apps.
  • The experimental WinML APIs have been removed from this release and will be included in a future release.

The following bugs have been fixed:

  • #​10572 Using App Window.Titlebar in child window causes main window hover UI to flicker badly
  • #​10464 Splitbutton Incorrect height
  • #​10524 TabViewItem Header Text has uneven padding when TabWidthMode="SizeToContent"
  • Users cannot use the Album and other details pages when sidebar (navigation view is collapsed
  • TabView: improper usage of GetFocusedElement
  • TabView: RequestClosedTab method

  • Resolved an issue related to versioning mismatches between WIndowsAppSDK and Windows SDK NuGet packages, which can cause new projects to fail to build out of the box. For more information see Windows App SDK GitHub Issue #​10467 Addressed a regression where the mouse wheel input was ignored if the "Scroll inactive windows when hovering over them" setting was disabled, making windows appear perpetually inactive. For more information see Windows App SDK GitHub Issue #​10091
  • Addressed a deployment bug where failing to set $(WindowsPackageType)=MSIX in the project file prevents the Deployment Manager from being added, causing apps to require admin privileges unexpectedly. For more information see Windows App SDK GitHub Issue #​8182

WinAppSDK 1.7.2 is the latest stable version of WinAppSDK providing new features and improvements to the platform. WinAppSDK 1.7.2 introduces exciting new features designed to bring artificial intelligence (AI) to your products with the power of Phi Silica and Windows AI APIs.

Whats new in WinAppSDK 1.7.2:

  • Phi Silica, Microsoft's most powerful NPU-tuned local language model, you can specify it to perform common tasks like summarizing a piece of text, rewriting a piece of text for clarity, and converting text to a table format.
  • Image Description APIs enable the generation of textual descriptions of images.
  • Text recognition, also known as optical character recognition (OCR), detects and extracts text within images, converting it into machine-readable character streams.
  • The 'ImageScaler' APIs can increase the sharpness and clarity of an image and upscale the image by up to 8x its original resolution.

The define is now the yymmdd date of the build, and the Patch value is the mmdd date. This change provides better runtime information on the version being used without changing any variable sizes or the version scheme. (RuntimeCompatibilityChange: N/A, header change)
  • Fixed a potential issue in the Bootstrapper if it is used to load a 1.6 or earlier version of WinAppSDK. For more info, see GitHub issue #​5349. (RuntimeCompatibilityChange: N/A)
  • Fixed an issue where using MSBuild to build a single-project app could incorrectly fail with a build error if it didn't have a correct launchSettings.json. (RuntimeCompatibilityChange: N/A, build .targets change)
