I have seen a couple old posts on this, but none of them were able to solve my problem. I am using AJAX 3.5 and have uploaded a web site to my shared GoDaddy hosting account. I have spoken to their support, but they do not know how to fix the problem. They did know that AJAX 3.5 was 'installed' on the server (I say it like this because it is included in the framework now).
I have created a basic testing ajax enabled web site. It works on my development machine, but on GoDaddy's servers it gives the error: 'Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. The system cannot find the file specified.' All the pertenant information in web.config is the 3.5.0.0 versions.
Any ideas? Their support is no help.
