I’ve released version 1.1 of my open source project MVVMT4 today.
It uses T4 Templates for generating view models, and views for WPF, Silverlight, Windows Phone using T4 Toolbox and MVVM Light
On Nuget! Type in "Install-Package MVVMT4"
Now in version 1.1: Conforms to StyleCop rules, and optional Unity DI container for ViewModels.
