Uno.WinUI is missing .Net 8 Windows lib output.

[IsmailHassani]

Current behavior

Building/running the .net 8 windows head generates an error.

C:\Users\ismai\.nuget\packages\microsoft.windowsappsdk\1.4.231008000\buildTransitive\MrtCore.PriGen.targets(657,5): error MSB4096: The item "C:\Users\ismai\.nuget\packages\uno.winui\5.0.48/lib/net7.0-windows10.0.19041.0/Uno.UI.Toolkit.pri" in item list "PackagingOutputs" does not define a value for metadata "ProjectName".  In order to use this metadata, either qualify it by specifying %(PackagingOutputs.ProjectName), or ensure that all items in this list define a value for this metadata.

When i check the nuget package i see a missing net8.0-windows folder under lib

Expected behavior

Should run out of the box

Thanks for the report. net8 missing is generally not a problem, though #14448 may be somehow related but this is not showing in our standard tests for net8.0 builds.

This may also be caused by microsoft/microsoft-ui-xaml#8857. Are you building a library?

[IsmailHassani]

Yes, I'm building a library for the Uno platform. But the error occurs in a sample project referencing this library.

[jeromelaban]

Then this will be microsoft/microsoft-ui-xaml#8857. Can you try adding the workaround specified there?
