Hi ALEX,

Please, find below my reply to the support ticket:

I'm sorry for this error happening on your side. The .NET Runtime throws the InvalidCastException error when there are ambiguous types loaded in the application memory (in this specific case, Visual Studio).

The error message you sent us denotes that the temporary assembly the Telerik VSExtensions create is the reason for the error. It gets created during the project creation and/or project reconfiguration. Can you try closing Visual Studio and loading the project again?

Please, try the following steps as well:
  • Close all Visual Studio instances
  • Start a Windows Explorer and navigate to the folder:
    C:\Users\[YourUserName]\AppData\Local\Temp\Telerik\ShadowCopy
  • Delete all the subfolders there
  • Load the project again

We will do our best to have this fixed for the upcoming Q1 2011 release of RadControls for ASP.NET AJAX.


Kind regards,
Erjan Gavalji
