I am trying to run a silverlight application on a Windows 2003 server. I am getting the following error in Visual Studio 2010.
Could not load file or assembly 'System.Windows.Controls.Data.DataForm.Toolkit, Version=126.96.36.199, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
I installed both Silverlight 4 and 5 toolkits on the server and add the mine types in IIS:
When I run the silverlight app on my local machine it runs fine and there are no issues.
