ObservableObject attribute doesn't work after update to Visual Studio

[JNickVA1]

Type of issue

Code doesn't work

Description

After I updated Visual Studio to Version 17.9.1, the ObservableObject attribute no longer seems to work. None of my properties that were accessible previously are available now in my xaml or in the same C# code where the properties are defined.

Have you tried doing a clean and rebuild. And if that doesn't work deleting the bin and obj folders and then rebuilding?

I have done a Clean and Build, deleted the bin and obj folders, and everything else I can think of. Apparently, I'm not the one developer having issues after updating Visual Studio to 17.9.1. Several others who also use the CommunityToolkit.Mvvm have experienced similar issues. The only recourse was to rollback to 17.8.5.
