    I installed and unlocked the dll files from the telerik website and added them to my toolbar in vs 2010. When I add the control from the toolbar to my sliverlight xaml file I get the following error:

    Could not load file or assembly 'Telerik.Windows.Controls, Version=2010.2.924.1040, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

    And the designer does not show the file anymore.

    I searched the forum and the Internet but I didn't find any working solution. Thanks in advance for your help.

    Hi Omid,

    Sorry for the delay in my reply. We are preparing our next release and we were not able to handle your request earlier.

    I believe you downloaded the zip file with the free controls and extracted it to a custom folder.
    The error comes from the fact that Visual Studio doesn't have any other information with regards to the dependent assemblies of one assembly.

    I suggest that you get the Telerik Silverlight VSExtensions and use them to create your project. You will get a wizard, which will help resolve the correct assembly dependencies during the creation of your New Telerik Silverlight Project.

    Let me know if that helps.

    Kind regards,
    Erjan Gavalji
