Versions

There are three versions of the library available:

Cross-Platform Edition
This supports .NET 4.5, Mono 4.5, Windows Store, Windows Phone (WinPRT), Xamarin.iOS and Xamarin.Android with a Portable Class Library and a set of platform-specific framework DLLs. This is the preferred release as it automatically detects your platform and installs the right things with Nuget. Install the MVVMHelpers.PCL version for this

WPF (3.5, 4.0 and 4.5)
This version is the older and more complete version which includes a variety of classes for .NET in general as well as MVVM, Behaviors and UI services for WPF.

Windows Store Apps (8.0, 8.1)
This version is newer and is a derivative of the original WPF version. It includes base MVVM support and a port of the Blend behavior system (since that was unavailable at the time).
