What do I have to change in my web.config in order to have the new toolkit use the ASP prefix?

I currently have this:

<controls>
        <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      </controls>

I tried changing the Version and PublicKeyToken but that did not work. I may have had the wrong values when I tried it.

Thanks,

Tim

 I believe you would have to do this when you add the reference at the top of your aspx page.

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>

There's a way to do this globally through your web.config file and I can't seem to get it to work.

 You're right.  Try adding these then and see if it works for you.

<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add tagPrefix="asp" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit"/>
