Godaddy, asp.net, IIS7 and system.web.extensions error

When publishing asp.net ajax enabled website with iis7 on godaddy, you need to add system.web.extension.dll manually to your bin folder.

This is possibly because godaddy is having newer version of ajax toolkit. If you are using "Version=1.0.61025.0" then copy the "System.Web.Extensions.dll" from your "C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025" folder to "bin" folder of your published website.
