Pull request overview
This pull request addresses issue #52057 by disabling the up-to-date optimization in dotnet-run-file when #:project directives are present in the source file. The up-to-date check cannot currently detect changes in referenced projects, so always rebuilding when project directives are present ensures correctness.
Key changes:
- Added a check in
NeedsToBuild()to skip the up-to-date optimization when project directives exist - Added a comprehensive test validating that projects with
#:projectdirectives always rebuild, even when the main file hasn't changed
