AJAX Toolkit 'unknown server control' Error

I just installed Ajax Toolkit. The controls are available in my Toolbox, but when I insert them in a page, Visual Studio underlines them with the error message "unknown server tag".

I googled the problem and found several ideas :

  • check if the DLL is in Bin folder
  • check if ajaxToolKit tags prefix is registered in web.config and make sure I'm not using a different prefix in my pages
  • check if the DLL is registered in the pages with <% @ Register ... %>

Unfortunately all of this is fine, but I still can't get the controls to work. Is something else missing ?

EDIT : My environment is ASP.Net 2.0, Ajax Extensions 1.0, Ajax Toolkit 1.0.20229, Visual Studio 2005

It sounds that you might have the wrong .Net version of the Ajax toolkit installed. Check http://ajaxcontroltoolkit.codeplex.com/releases/view/43475

I think its a bug and a bogus message that keeps coming time to time with Ajax control toolkit. Sometimes closing the VS and restarting helps. If that does not help, try removing the control toolkit and re-referencing again.
