The Net.Tcp Port Sharing service makes it possible for multiple Windows Communication Foundation (WCF) services that are using the net.tcp protocol to listen on a single TCP port. Port sharing reduces the number of firewall exceptions that are necessary to host WCF services by allowing the use of common ports that are already open.

Task Reference

Your application must use the Net.Tcp Port Sharing feature. The developer writes the application to use the NetTcpBinding binding (a .NET 3.0 Class) to connect WCF applications. WCF exposes port sharing as a configurable option on the binding.
