Version

2.0.240111.5

Summary

After I upgraded the C++/WinRT version, my WinUI3 project failed to build. After switching to the previous version, it built normally.

Try cleaning the project before building after upgrading cppwinrt

Try cleaning the project before building after upgrading cppwinrt

I manually cleaned up all the generated files, but I still get the same error, with some linking errors. After I switched back to version 2.0.230706.1, the error disappeared and it built successfully.

The full MIDL options displayed in VS is

Looks like the custom idl include directories was lost in one of the generation steps.

I found out that #1381 is causing my project to break.

Is this result intentional? @Scottj1s

For Xaml issues please use this repo: https://github.com/microsoft/microsoft-ui-xaml

[YexuanXiao]

For Xaml issues please use this repo: https://github.com/microsoft/microsoft-ui-xaml

I’ve found it’s due to a change in the nuget/Microsoft.Windows.CppWinRT.targets file from #1381, so it’s unrelated to the XAML repository.

[kennykerr]

Yes, but that largely serves to support Xaml and the change was made by the same team. I'd love to help but that's your best bet at getting the issue in front of the appropriate developers (they don't monitor this repo).

[Scottj1s]

@YexuanXiao I'd be glad to take a look at a repro project, if you have one

I have a repository that replicates the problem: https://github.com/yexuanXiao/PlayerWinRT

@YexuanXiao thank you for the repro. A fix has been made to CppWinRT: #1404
