Additionally, there is also a blog article titled "Intercepting WCF Traffic with wcfproxy", and a short tool tip video demonstrating wcfproxy.

Intercepting WCF Traffic with wcfproxy
Windows Communication Foundation (WCF) is still a commonly used .NET framework for client-server communication. Specifically, when Net.TCP is used for transport, the binary encoding of messages makes the network communication challenging to analyze. This in turn poses an obstacle for the security analysis of WCF-based software products. For this reason we developed “wcfproxy”, a tool to facilitate the analysis of Net.TCP-based WCF communication.
