Hello,

I'm in the progress of migrating our WPF from .Net 4.7.2 to .Net Core 6
I run into issues with our test projects that reference WPF and use Microsoft Fakes
Please see my demo repo here:
https://github.com/RoyRosenberg/msFakesWPF

Basically, the problem can be described like the following:
- Class Library project with true
- The project contains ControlDemo class that inherits from UserControl class
- MSTest project with reference to the class library project
- I added fakes assembly to the class lib. project

When trying to compile, I got the 20 errors related to Fakes generation, one of them is:

`Error CS7069 Reference to type 'DependencyObject' claims it is defined in 'WindowsBase', but it could not be found`


Please help me find out the problem
Thanks in advance,
Roy
