ASP .NET 2.0 Web.Extension error despite web.config modification

[Hk]

Hi,
I'm testing your ajax controls on ASP .NET 2.0 target framework.
I get the following error:

The type 'System.Web.UI.IScriptControl' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

Despite the following changes:

1. I installed Microsoft .NET 2.0 AJAX extensions 1.0 and also Microsoft ASP .NET 2.0 AJAX Templates for VS 2008 from which I chose "New AJAX Web Application" and changed the target framework to 2.0.

2. I modified my web.config file to run AJAX from a tutorial I found on the web (http://asp.net/ajax/documentation/live/configuringASPNETAJAX.Aspx):

What should I do to make the controls compile?
