The LoadApplication(new HelloXUP.App() ); call need as specified in https://developer.xamarin.com/guides/xamarin-forms/platform-features/windows/installation/universal/ fails with "cannot convert from 'HelloXUWP.App' to 'Xamarin.Forms.Application'".
I've tried changing the base type of App to Xamarin.Forms.Applicaiton but no go.
Probably something simple. Any ideas?
