Building truly Universal applications with Azure, Xamarin and MVVM
summary
Shows a concrete conversion: an Android MVC app that parses YouTube HTML for 866 views is refactored into a shared dotnet standard data library with a testable IYouTubeService, RelayCommand-based view models, and SimpleIoc registrations. MVVM Light snippets and data binding replace UI code, unit tests use a fake service and run green, and the same view models drive Android, iOS, UWP and Xamarin.Forms UIs. MVVM Light claims about 3.3M downloads and the demos run end to end.
