@amirvenus have you tried adding the following package https://www.nuget.org/packages/Xamarin.Google.Android.Material ?

That did the trick.

Is this documented? I was hoping the upgrade-assistant tool would take care of it itself

Thank you!

However, I had some other issues with the Resource generation so I had to use some workarounds and csproj properties

dotnet / android
