I downloaded Q2 2010 Silverlight 4 DLL and tried to use the RadChart control in my VS 2008 Silverlight project. I am getting this error suggesting that the Method does not exists.
But if I go back to the Q2 2010 Silverlight 3 DLL, then there is no compilation error. Has there been a changed in the Silverlight 4 version of the DLL? What code change do I need to make it work on Silverlight 4 DLL. Thanks in advance!
Error 45 'Telerik.Windows.Controls.Charting.ItemMappingCollection' does not contain a definition for 'Add' and no extension method 'Add' accepting a first argument of type 'Telerik.Windows.Controls.Charting.ItemMappingCollection' could be found (are you missing a using directive or an assembly reference?)

FIXED. After I installed VS 2010 and upgraded all my projects to .Net 4.0 and Silverlight 4.0 runtime, the error disappeared. Thanks.
