I looked at Ajax 4, but on my XP box I had errors I couldn't work with. So I uninstalled Ajax 4 and installed Ajax 3.5, then copied the DLL files to all the Bin directories of the web sites on the development box.
I thought everything was fine, but after several hours of development, I again started getting the error:
AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll.
How can I remove all references to Ajax 4 so I stop getting these errors, it is very frustrating. I am on a Win XP box owned by the government, they will not be upgrading to Win7.
