   Whenever I try to use telerik:StyleManager.Theme="Vista" on any RadControl, my Visual Studio 2010 design mode errors out and I wont be able to view the designer. See the attached snapshot. I get this error after upgrading to v.2011.1.419.1040 of RadControls for Silverlight
  

   
  Am I missing any references, I already have Telerik.Windows.Themes.Vista.dll being refered.

  
  <telerik:RadColorPicker IsDropDownOpen="True" Grid.Row="3" Grid.Column="1" Margin="30,5,10,5" ColorButtonStyle="{StaticResource ColorButtonStyle}" telerik:StyleManager.Theme="Vista" />

  Hello,

   Do you have reference to Telerik.Windows.Controls.Input.dll?

  Yes I do have the reference to Telerik.Windows.Controls.Input.dll. Screen shot attached. If I build and execute the project I won't have any issue in run time though but only in Design time I get this error.

  Hi Suresh,

   
  Can you verify that all references to the Telerik assemblies are with the same version? 
  Once you ensure that the assemblies are with the same version yoy may delete the Obj folder. 
  Then try to rebuild the application and let us know whether the problem still exists.

  Upgrading to latest version fixed the issue.
