Error opening FileCards.sln on Mac

[arolson101]

When I open the FileCards.sln or FileCards.csproj using Visual Studio for Mac 17.4.2 (build 17) (on an M1 Mac) I get this error:

The type initializer for 'MonoDevelop.MonoMac.XamMac2ProjectFlavor' threw an exception.

The problem is likely that you don't have Xamarin.Mac installed:

Xamarin.Mac not installed. Can't find /Library/Frameworks/Xamarin.Mac.framework/Versions/Current/Version.

Please install Xamarin.Mac and try again.
