I’m also hours into the problem, but this did not work for me.
I am trying to install the AjaxControlToolkit in Visual Studio 2008 in Windows XP. The dll shows up in the Project Explorer. But I can not add it to the toolbox.

MMC won’t let me add .net framework 2.0 config , but it did let me add .net 1.1 framework config which seems to work the same way. (I have .net framework 3.5 sp1 installed). I easily followed instructions, but I still get “aspnethostingpermission failed”.

Johnny B: I had the same issue.
I solved it like this:
First open Runtime Security Policy->Machine->Code Groups.

Then rightclick “All_Code” and choose “New…” in the popupmenu.

Enter a suatable name and click next.

In the condition type dropdown choose URL. and in the URL textfield enter the url to your site followed by “/*”. Click next.

Select “full trust” in the dropdown. Click next and then Finish
