Mvvmcross 4.1 Upgrade Issue Isfragmentcacheable Not Found

Getting a compilation error after upgrade to mvvmcross 4.1 in Linker task: The 'LinkAssemblies' task failed unexpectedly. Xamarin.Android.XamarinAndroidException: error XA2006: Ref

Solution 1:

You should remove the MvvmCross.Droid.Support.V7.Fragging package since this is included in MvvmCross.Droid.Support.V4 now.

After that update your namespaces, and the app will work again!
