AJAX errors

I am trying to use the Ajax toolkit. Locally it works but when I publish the page to my site it fails to load with the following error:

Reference required to assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' containing the base class 'System.Web.UI.ExtenderControl'. Add one to your project.

What do I need to do to get the site to work with the AJAX toolkit?

Thanks

AJAX version 3.5 itself is installed on the servers GAC but not the actual AJAX control toolkit. You will need to make sure you upload the AJAX tool kit assembly in your applications Bin folder.

 

Thanks Ray

I have uploaded the assemblies into the bin folder already and still get the error.

You have a URL we can look at?
