MvvmCross is a MVVM framework for XAML platforms, similar to Caliburn Micro and MvvmLight. Unlike its competition it very much focuses on portability and code reuse across all supported XAML platforms (WPF, Windows Phone and Windows Store), and the Xamarin platforms as well (Xamarin.iOS, Xamarin.Android and Xamarin.Mac). Therefore it has its own approach to creating converters, allowing them to be implemented in a portable class library and reused on all supported platforms.
