Here we go! After the Microsoft team released version 5 of Silverlight yesterday, MVVM Light is available for this version of the framework too. I did not create the installer yet (that will take a few more days), but you can download the source code and build it yourself easily.
With this latest release, this puts the number of supported frameworks to 8: .NET 3.5 SP1, .NET 4, Silverlight 3, Silverlight 4, Silverlight 5, Windows Phone 7.0, Windows Phone 7.1 and Windows 8 (preview).
Dropping Silverlight 3 and WP7.0?
That said, I am considering dropping old frameworks now for new development. So here is a chance to make yourself heard, tell me if you think that it is OK to drop Silverlight 3 and/or Windows Phone 7.0 and to concentrate on the 6 other supported frameworks:
Thanks and happy coding!
