In traditional socket programming scenarios, (multi) threading is use to create a responsive server or client. I have bypassed that route and shown you how to use asynchronous sockets directly.
The server is built with an asynchronous socket, so execution of the server application is not suspended while it waits for a connection from a client. The application receives a string from the client, displays the string on the console, and then echoes the string back to the client. The string from the client must contain the string "<EOF>" to signal the end of the message.
