How to make TCPClient window to communicate with TCPServer in WPF using C#?

Question

I am struggling to make my TCPClient to communicate with TCPServer, i have TCPServer that must receive messaging as well ports to be listened. Can anyone help me, there is no issue with firewall or anything. Its just my client must be able to communicate with the server to listen to my ports. The application is WPF and im using C# as a window application.
