Don’t forget about this one. It’s still unresolved on 8.3.92.1915, but the error message is different:

public class MainActivity: Activity
{
    public override void onCreate(Bundle savedInstanceState)
    {
        base.onCreate(savedInstanceState);
        ContentView = R.layout.main;

        new SubClass().doSth("1234");
    }        
}
public class SubClass : BaseClass1 {
    public override void doSth(string v) {
        Log.i("","doSth in Sub: "+v);
        base.doSth(v);
        /** Different error message:

Yep. I’ve undone this change as it causes this new issue. I can only suggest creating a workaround for now until I find a proper fix for this.
