    I am using the Terleik silverlight 4 Controls Version 2012.2 725 (Jul 25, 2012),  previously i have used "RadControls_for_Silverlight4_2012_2_0725_TRIAL_hotfix" dlls for silverlight 4 , it was working properly. Currently am using the dlls from "RadControls_for_Silverlight4_2012_2_0725_DEV_hotfix" (purchased). Am getting the below error for all the controls, can you tell me what i am missing?

    The type or namespace name 'RadComboBox' could not be found (are you missing a using directive or an assembly reference?)

    its giving error in "MainPage.g.i.cs"  and by doing resolve it is fixed temporarily. but while building same error am getting. Please help me to resolve this.

    Hello Sivaraman,

    Please follow these steps:

    1. Open the project and remove all Telerik's references.
    2. Save the project and close it.
    3. Open the project directory and delete "Bin" and "Obj" folders.
    4. Open the project and add the references.
    5. Build the project.

    Do you get the same errors again?

    You can also check this MSDN forum thread for a reference.

    No, this did not work for me.  How did I get here?  These are the steps.

    Originally running VS2010 with Telerik Silverlight Controls (TSC).  Got a project from a customer, found out it was VS2012.  Installed VS2012 on my computer.  When opening the project in VS2012, found out I had no TSC(s).  Had to go to the Telerik website and relaunch the TSC installer.  Once TSC installer ran, I could then choose "Install TSC for Visual Studio 2012".  Install went fine.

    Now, re-opened the project in 2012 (had to delete and re-add TSC in the References section becase all 6 TSC(s) had yellow icons on them).  However, there were no TSC(s) in the toolbox.  To try and fix that, went to "Menu -> Telerik -> RadControls for Silverlight -> Launch Toolbox Configurator".  This was done to try and rebuild the TSC(s) into my toolbox.  VS2012 rebooted, however, still no TSC(s) in the toolbox, and I still get the "The type or namespace name Telerik could not be found" in all the CodeBehind software.

    Followed the suggestion in this thread to Clean and delete OBJ and BIN data -- no help.
