WinRT Interface Implementation Without partial Declaration

[ghost1372]

i get following warning when aot is enabled:
Class 'FreeLibrarySafeHandle' implements WinRT interfaces but it or a parent type isn't marked partial. Type and any parent types should be marked partial for trimming and AOT compatibility if passed across the WinRT ABI. (https://github.com/microsoft/CsWinRT/tree/master/src/Authoring/WinRT.SourceGenerator/AnalyzerReleases.Shipped.md)

Class 'UnhookWindowsHookExSafeHandle' implements WinRT interfaces but it or a parent type isn't marked partial. Type and any parent types should be marked partial for trimming and AOT compatibility if passed across the WinRT ABI. (https://github.com/microsoft/CsWinRT/tree/master/src/Authoring/WinRT.SourceGenerator/AnalyzerReleases.Shipped.md)

I assume these implement IDisposable and due to that the CsWinRT AOT analyzer is flagging them. If you are not passing these across the WinRT ABI, it should be fine to ignore for now. We have found that the analyzer is noisy with IDisposable as it is commonly implemented and have plans on trying to address it which is tracked by microsoft/CsWinRT#1968.

Thank you @manodasanW
I’m experiencing some issues with PublishAOT. Where is the best place to report them? I’m getting different results between Debug, Release, and Publish (MSIX) builds. I’m working with WinUI, but I don’t think the WinUI repo is the right place for this.

If the issues are with respect to CsWinRT projections / WinRT APIs (including the ones CsWinRT generates for WinUI WinMDs), you can report them in the CsWinRT repo.

Fixed in #1474, which made the generated SafeHandle types partial.
