This tutorial walks through creating the client & service. The difference is, instead of implementing a calculator, you'll want to implement your code for whatever the service does.

One question, though, why do you want the service to display a yes/no and not the client?

FWIW, I once wrote a series of blog posts that describe how to approach development of Duplex WCF services with Test-Driven Development.
