RadChart Not Parsing

[J]

Version 2011.2.712.1040

When InitializeComponent I get an XamlParseException "The type 'RadChart' was not found".  
I have included in this module:
Telerik.Windows.Controls
Telerik.Windows.Controls.Charting
Telerik.Windows.Controls.GirdView

This is using MEF where this RadChart is in a Module view.  I've tried removing the reference then dragging from the tool box to add again, eliminate bindings, using <telerik:RadChart />.  One would think at least an empty control would work.

Your tools shouldn't cause this much trouble.  It has been more than once where I had to reinstall your products and lose days of work troubleshooting problems.  I also imagine Microsoft can be the blame as well.

Hello,

I believe that the  cause of the problem is that your project is targeting Silverlight version 5 and you have referenced Telerik Controls for Silverlight 4 assembly(ies).

Please check and if this is not the cause of the problem do let us know.

No, I checked everything, each project.  It is targeting Silverlight 4.  .NET 4.0.3

I found my problem.  I was using mef to use the chart in the main view.  I didn't reference the Charting library in the main view.  Sorry for my confusion.
