    Hello! I got the same error... However this error pops up during my "installation" of the AjaxControlToolkit - By installation I meant when I was creating a new tab, namely AjaxToolkit, in the Toolbox. I did "choose item" then browsed to the dll, but no tab was created because of the following error message poping up:
    1. I believe I have got the correct version of dll for this ajax toolkit from codeflex - it's for visual studio 2005, .net framework 2.0
    2. I couldn't find System.Web.Extensions in the GAC [c:\windows\assembly to make a reference. Where else can it be?
    Please help me with this installation of ajax control tool kit on Visual Studio 2005. So frustrated. Thanks
