I am betting you also get this same error with ANY Ajax Control Toolkit items, not just the extender.  Does your project have a reference to the Ajax Control Toolkit DLL file?  Also since you are using VS2008, you may need to reinstall VS.  I have had some problems popup on me with this build where I have had to reinstall before it would work.  But make sure the references are in place before anything.
Let me konw how it works out - This is definitely a configuration error, not a coding error.
