This is strange, because looking at the history of Csla.Xaml.Wpf and Csla.Xaml.Shared, nothing has been changed for months.

I wonder if some dependency (like a WPF package?) changed out from under us?

Hello Rockford Lhotka,
It's quite peculiar; I've reviewed everything before posting the history, yet nothing seems to have changed regarding this issue.

I search on Visual Studio a problem similar:
https://developercommunity.visualstudio.com/t/Unable-to-run-WPF-app-SystemWindowsMar/10722395
dotnet/wpf#9582

I'm experiencing issues with Visual Studio 17.12 Preview 1, and have switched to Visual Studio 17.11 to compile my applications until a resolution is found. I'm uncertain if this version was compiled using the stable or preview release. If it was compiled with the preview release, then it should be recompiled using the stable version.

I generally do use the preview of VS - and obviously got burned this time 😞

Before uploading version 8.2.7, could you test the library? I've looked into the GitHub issues for dotnet core and noticed that the problem is associated with the .NET Core 9.0 preview.
