Hi,
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:
System.IO.FileLoadException
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.
