AJAX :: How To Use CDN For MicrosoftAjax.js With .NET 4 & Control Toolkit 40412

Looks like there aren't a lot of users using the Ajax Control Toolkit 40412 and the Microsoft Microsoft Ajax CDN because I can't find any information on how to get the MicrosoftAjax.js and MicrosoftAjaxWebForms.js files to be linked to the CDN.

First issue:Ajax Control Toolkit 40412 seems to be using its own customized version of MicrosoftAjax.js and MicrosoftAjaxWebForms.js. Toolkit's version

is 4.1.40412.2, while the version that come with ASP.NET Ajax 4 is 4.0.30205.0. By default when using the toolkit the version is swapped to the toolkit's version. While the ASP.NET Ajax 4 version is hosted on the CDN (http://www.asp.net/ajaxlibrary/CDNAjax4.ashx)
the version with the Toolkit is not (http://www.asp.net/ajaxlibrary/CDNACT40412.ashx), which doesn't make any sense because all the other files are hosted. Therefore, a CDN version of MicrosoftAjax.js and MicrosoftAjaxWebForms.js is UNAVAILABLE when using the Ajax Control Toolkit 40412.

Second Issue:Why not use the ASP.NET Ajax 4 version of the the MicrosoftAjax.js, after all its version 4. The version can be swapped out by adding a Script Resource Mapping to the Application_Start event in the Global.asax.cs.

void Application_Start(object sender, EventArgs e)
{
ScriptManager.ScriptResourceMapping.AddDefinition("MicrosoftAjax.js", new ScriptResourceDefinition
{
Path = "~/Scripts/MicrosoftAjax.js", [code]....

However, when the version is changed to the ASP.NET Ajax 4 version the following error is given:

"AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll."

It doesn't matter if you are using the ToolkitScriptManager or ScriptManager you will always get this error when not using the version of
MicrosoftAjax.js that comes with the AjaxControlToolkit.So how can one use the Microsoft Ajax CDN for the MicrosoftAjax.js and MicrosoftAjaxWebForms.js with ASP.NET Ajax 4 & Ajax Control Toolkit 40412?

One other note. The new attribute EnableCdn="true" is of course rendered completely useless when using the Ajax Control Toolkit because the idea is that the MicrosoftAjax.js and MicrosoftAjaxWebForms.js files would then be linked by references to the CDN. This does not happen with the Toolkit because as described the Toolkit replaces the those files with its own. I was very surprised to find out that all my excitement about having CDN support was made void when I included the Toolkit in my project.
