@kni Can you provide as with a full repro project in a zip? I copied the code from the issue but it's full of build errors.

kni commented 2 days ago

Foo.zip

ramezgerges commented 3 hours ago

@kni I can't reproduce on Desktop or Android. I tried the Uno.Sdk version in the zip and also the latest Uno.Sdk.

Maybe it depends on the workload?

My dotnet workload list is:

Installed Workload Id Manifest Version Installation Source

android 34.0.143/8.0.100 SDK 8.0.400, VS 17.11.35327.3 ios 18.0.8303/8.0.100 SDK 8.0.400, VS 17.11.35327.3 maccatalyst 18.0.8303/8.0.100 SDK 8.0.400, VS 17.11.35327.3 maui-windows 8.0.82/8.0.100 SDK 8.0.400, VS 17.11.35327.3

To the point. I reproduce also https://github.com/unoplatform/uno/issues/14792
