asp.net ajax和.net 4 TypeForAjax的问题​​未定义

Question

After changing my target framework from 3.5 to 4, I had the symptoms and followed the steps described in http://dotnetspidor.blogspot.com/2011/09/last-time-i-got-following-error-http.html

Now I get an error on one of my pages telling me that the ajax javascript representation for the page is undefined. does someone know what could be wrong?

Thanks!

Update: ok so it seems we're using an old version of ajax.net that isn't compatible with .net 4, so Ajax.Utility.RegisterTypeForAjax does nothing. I've been searching for an updated version of the control but can only find one called ajaxpro. while this seems to be a new renamed version of ajax.net it's in a different namespace and the project has thousands of references. I would really like to find the latest ajax.net component released but haven't been able to get it all day. could someone please point me in the right direction?

Update: maybe the problem lies in my web.config, so here it is
