MvvmCross crashes on app start with "Method 'Array.Empty' not found" exception

Question

I have recently updated my Xamarin.Android app MvvmCross package from 4.1.4 to 4.1.5 and now unable to launch my app. Couldn't even debug the issue as long as my code doesn't get any control before the crash.

System.MissingMethodException: Method 'Array.Empty' not found.

• clean / rebuild doesn't help
• rollback to 4.1.4 restores the app

This seems to be a current issue with MVVMCross and Mono. More information about it here: https://github.com/MvvmCross/MvvmCross/issues/1330
