                To extend this theme to include the toolkit controls:
                1. Install the Silverlight Toolkit for Silverlight 4
                2. Add a Toolkit control to your project from the toolbox. This will add references to toolkit assemblies.
                3. Change the "Build Action" for ToolkitStyles.xaml to "Page"
                4. Uncomment the resource dictionary include above.
                
                If you do not intend to use toolkit controls, delete this comment and the ToolkitStyles.xaml file.-->
