I am demoing Rad Controls for use in an application that I am developing. When I open the project in Expression Blend 4, I am unable to even get started. On a page on which I am using a RadGridView for example, I get an "Unable to cast object of type 'Telerik.Windows.Controls.RadGridView to type 'Telerik.Windows.Controls.GridView.GridViewDataControl" error message and cannot access properties for any of the elements on the page.
The project builds error free in VS 2010 and runs properly.
