TCP/IP server/client multiconnection using C# and receiving public ip address of client

Question

I need to write an application using C#, which will connect a client to a server with a static IP address.

The server and clients must be able to send and receive message at the same time. Also, I need to log the information with respect of clients public address as well.

How can I make it using C#?

Shall I use TcpListener / TcpClient or is there any other method which can make multiple connections?

If you really want to go low level to TCP/IP and own message parse/serialize/deserialize, you can use SocketAsyncEventArgs for high performance code, but it is not as easy as with TCPListener/TCPClient.

Question is, why not to use for example WCF/IIS ?
