Failure loading MapView after upgrade to 200.7,

[JoeHershman]

I just upgraded my app to use 200.7 and now when I try to load MapView it crashes.  I am looking through getting started, don't see anything I need to change.  I have been using net9.0 for a while on the 200.6 release

Doing a little more debugging and I get this before the error listed above

System.DllNotFoundException: __Internal

Sounds like a restore/deployment or target framework issue. Is your .NET MAUI up to date? Try deleting bin/obj folders and restart visual studio, or perform a manual "dotnet restore" from command line.

Ran a clean and deleted bin/obj folders.  Deleted the app from device also.

Everything is now running with 200.7.  Also, have the new barcode scan working with FeatureForm in the 200.7 toolkit
