AjaxControlToolkit package in the C# 4.5 template does not work as expected. If try to use an ‘AjaxControlToolKit’ control on the page, a client side error is thrown on the browser which is “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.”
Even change from script manger to ToolkitScriptManager does not solve the problem.
