Re: Unable to use new ajax contro tool kit

The new toolkit is using .NET 3.5 and the System.Web.Extensions you are referencing to is the ASP.NET 2.0 Ajax.

You have to change the System.Web.Extensions-reference in your web.config to the ajax that ships with .NET 3.5.

If you are using .NET 2.0 then you can get the latest version to it from here.

Open the web.config file and change the version to "3.0.30930.28755" from "1.0.61025.0". Also change the PublicKeyToken to the current assembly' PublicKeyToken.. Changing these two things will solve your problem.
