MvvmCross is a cross-platform MVVM framework. It enables developers to create apps using the MVVM pattern on Xamarin.iOS, Xamarin.Android, Xamarin.Mac, Xamarin.Forms, Universal Windows Platform (UWP) and Windows Presentation Framework (WPF). This allows for better code sharing by allowing you to share behavior and business logic between platforms.MvvmCross is extendable by you. We strive to let as much code be configurable and overridable, to let the developer decide how they want to use the framework. However, the framework is very usable without doing anything.
