Getting an error when adding elements in AjaxControlToolkit.config file to ASP.NET project

I am trying to add a file - AjaxControlToolkit.config to the root of the application in ASP.NET and when i type in the first tag <ajaxControlToolkit> it gives me an error saying the element is not declared.  I tried to build and rebuild the project but no luck. Do i need to declare something in the web.config. i added CombineScriptsHandler.axd in the web.config.
All the ajax controls work as expected when i run the project but i wanted to speed it up a bit by creating the ajaxControlToolkit.config file but i can`t.
Am i missing something?

Thanks for your reply

Not all XML elements are recognized in the file, so you can ignore that error, and move on.

I did a tracing on the project and when i run the first time it gives me the same time loading all events as before i include the AjaxControlToolkit.config file hence not sure if it`s effective.

All i have in that config file is

<ajaxControlToolkit>
  <controlBundles>
    <controlBundle name="ajaxTools">
      <control name="Accordion"></control>
      <control name="AlwaysVisibleControlExtender"></control>
      <control name="ModalPopupExtender"></control>
    </controlBundle>
  </controlBundles>
</ajaxControlToolkit>

and then assigning the control bundle in the toolscriptmanager as:

<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" EnableCdn="true" EnablePartialRendering="false" runat="server">
            <ControlBundles>
                <ajaxToolkit:ControlBundle Name="ajaxTools" />
            </ControlBundles>
        </ajaxToolkit:ToolkitScriptManager>


Is this correct?     ...Thanks for your reply ...

If you are asking if the bundling configuration looks correct, then I believe that it is correct.
