Blend 2 cannot load xaml page containing a Silverlight Virtual Earth Map Control

I’m not sure why, but is seems that Blend 2 SP1 needs to compile a solution that is using the Microsoft.VirtualEarth.MapControl.dll first, then any solution with .xaml files that use the control will display without this exception in design view. What I needed to do to "fix" the issue what just Run the Project from within Blend. You can do this by pressing F5 or selecting the "Project – Test Solution" menu option.
