The error is caused due to the fact that ASP.NET runtime is not able to locate an assembly which has been said to be referred in the application configuration - web.config. All you need to do to resolve this error is either remove the reference of the said assembly form your application [if you're not using any components that are available within the assembly] -or- make the assembly/DLL available in your application which is more recommended. Here's how you do that.

On the development workstation - Please install ASP.NET AJAX 1.0.

On the production server - When you deploy your application if your server does not have ASP.NET AJAX 1.0 extensions installed, you will need to put the Systen.Web.Exntesions.dll in your dll which you can easily get it from

C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025

assuming your program files folder is in C: You can find more resources from the links below.

Install ASP.NET AJAX 1.0 from the following link: http://www.microsoft.com/downloads/details.aspx?FamilyID=ca9d90fa-e8c9-42e3-aa19-08e2c027f5d6&displaylang=en

That should also register the System.Web.Extensions assembly in the GAC.
