WCF / WPF Chat Application This article is about how to create a peer-to-peer chat application using Windows Communication Foundation (WCF) and also how to make it look nice using Windows Presentation Foundation (WPF). When I first started reading about WCF, the first place I looked was the MSDN WCF Samples (which I read a lot), but they weren't that great. I also found lots of chat apps based on the MSDN versions, which were no good, as they could not return the list of users within the chat application. I wanted to create a nice WPF styled app with the list of connected chatters.
