[Oded]

Hello 
I get the folloing exception when trying to add the telerik radchart control in the silverlight xaml user control.
I work on lightswitch and added a silverlight userconrol , already added the 3 dlls references to client and client generated projects.
I have folowed the instructions on the word document "Adding RadChart to a LightSwitch Solution" downloded from your site,
but something is missing.
I am stuck at this point and missing something to view the radcontrol. (so far I haven't mange to see any chart)
Thanks alot in advance for your help,
Oded

The exception: System.TypeLoadException  ->  Cannot find type System.Func`5 in module CommonLanguageRuntimeLibrary.

The control XAML:   (in bold the line that cause the exception (adding the radchart control))
