MVVM 101 - Model-View-ViewModel Architecture for Xamarin.Forms (also WPF, UWP, & More)

It is go time! Time for some architecture with MVVM, data binding, commanding, and more. In this episode I walk you through everything you need to know about MVVM, what it is, why you need it, and how it can help you be more productive and write less code that is more testable.

I break down MVVM with Xamarin.Forms, however most of the concepts are the same across WPF & UWP. Some key differences are that you have DataContext instead of BindingContext (WPF/UWP) and x:Bind instead of x:DataType - https://docs.microsoft.com/windows/uwp/xaml-platform/x-bind-markup-extension on UWP for compiled bindings (nothing available for WPF).
