Why does the source generator run twice?

[W2Wizard]

It seems like that the source generator runs twice, because of that there are multiple type definitions for the enum extension types.

Is there anything you can do?

This is a known issue that is caused by Visual Studio 2022 (version 17.2.6) and dotnet.

For more information see:
dotnet/sdk#26542, dotnet/wpf#6792, CommunityToolkit/dotnet#343

Workaround that can be used in the meantime to temporarily fix the issue:
