[Hiep]

Dear Telerik team,
I'm writing the code for the silverlight project with version 4.0. but I encountered an error.: The type or namespace name "RadComboBox" could not be found (are missing a using directive or an assembly reference?). First, The project due to a customer sent over to me. but lack of telerik library. 
Please, help me.

Hello,

Please, double check the version of the Silverlight assemblies - it should be *.1040 (build for SL4).

All the best,
