The answer may differ based on how the parent process was started. + +**Evidence supporting this:** +- Tests fail specifically on **Windows Desktop (net472)** - console handling differs between .NET Framework and .NET Core +- FSI shows `"> >"` (two prompts) - it's running but not processing input, suggesting it decided not to read stdin +- The stdin write completes successfully - data is in the pipe, FSI just isn't reading it + +### How to Test Hypothesis D + +1. **Check FSI's perspective**: Add `--readline-` flag to FSI to disable readline and see if behavior changes +2. **Check Console.IsInputRedirected**: Log this value from within the test process before spawning FSI +3. **Force console allocation**: Try `AllocConsole()` before spawning FSI to ensure a console exists +4. **Compare process creation**: Check if MTP uses different `ProcessStartInfo` settings + +--- + +## Next Steps + +1. [ ] Add diagnostic to log `Console.IsInputRedirected` in test process before spawning FSI +2. [ ] Try adding `--readline-` or other FSI flags that affect stdin reading +3. [ ] Research how MTP starts test processes and what console settings it uses +4. [ ] Consider if we need to explicitly set up console handles before spawning FSI + +--- + +## Conclusion + +~~The FSI stdin test failures were caused by a **race condition in async process output capture** that existed in the codebase but was hidden by xUnit v2's in-process execution model.~~ + +**UPDATE**: The original hypothesis appears to be incorrect. Multiple synchronization fixes have failed. Further investigation with enhanced diagnostics is required to understand the actual root cause. + +**Total Investigation Time**: Multiple CI cycles over several days, involving: +- Parallelization configuration attempts +- Console vs file-based diagnostic logging +- .NET Process async I/O research +- Race condition analysis and fix implementation (FAILED) +- Double WaitForExit pattern (FAILED)
