I have got this figured out now. Evidently, when you run client and
webservice projects in a signle solution, Visual Studio does not create the
proxy. I removed the webservice project and instead added a reference to the
webservice to the client project; Voila! Visual Studio created the proxy
class for me. Of course, I still had to tweak the proxy class, but getting
the proxy class created was 90% of the solution.
