You may see an error message The "LinkAssemblies" task failed unexpectedly when building a Xamarin.Android project that uses Forms. This happens when the linker is active (typically on a Release build to reduce the size of the app package); and it occurs because the Android targets aren't updated to the latest framework.

"Why does my Xamarin.Forms.Maps Android project fail with COMPILETODALVIK : UNEXPECTED TOP-LEVEL ERROR?"
