There was an error loading types from assembly 'Telerik.Windows.Controls.dll'
'Could not load file or assembly 'System, Version=22.214.171.124, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.'
This is what I get when I try to add any controls from the library. What I have is Silverlight 3 only. Since they say that installing SL3 would make it impossible to continue developing SL2 projects, I created a new Windows instance and installed SL3 only.
Seems that Telerik SL3 controls depend on SL2 system?
