Could not load type error for any webservice on ASP.NET 2.0 beta 2

[mrkurt]

I've built a few webservices locally that work just fine. Deployed
them to a server and I get the following exception. This exception
happens on even the most basic webmethod call. Hitting the webservice
without calling a webmethod brings up the WSDL and such as I would
expect, only when I make an actual call does this happen. Any ideas?

I am assuming you developed the web services in 2.0. Make sure your
target server is running 2.0 as well.
