VisualStateGroup not in System.Windows?

Sep 30, 2011 at 4:49 PM

Hi I'm new to WPF and I'm trying to get a theme to work that I downloaded. There is one error that is preventing the program from building:

Error 1 The tag 'VisualStateGroup' does not exist in XML namespace 'clr-namespace:System.Windows;assembly=System.Windows'. Line 200 Position 10. c:\users\greg\documents\visual studio 2010\Projects\BlackForm\BlackForm\DavesGlossyControls_v1.2.xaml 200 10 BlackForm

Does anyone know what's going on here? I added the downloaded xaml file to the solution and referenced it in app.xaml. I also added some namespace references to the top of the app.xaml file.

I'd really like to have this theme working so any help is appreciated
