Windows 8 TCP Server XAML Application in C #

Question

I recently developed a TCP Client-Server application using WPF and C # for Windows Desktop. Now I'm going to transfer it to the Windows 8 Metro app.

But it looks like the System.Net.Sockets namespace is missing from the Metro Apps SDK. (Therefore, I cannot use TcpListener, TcpClient, etc.) I also could not find a working example.

Is it possible to create a TCP-IP server as an application for Windows 8 Metro (using a different approach)? Are there third-party libraries available for this (free and open source, preferably)?

Please help me. Thanks in advance.

Answer 1

Instead, StreamSocket is recommended.

Here is an example from MSDN.

---

The socket provides sending and receiving over TCP, and the StreamSocketListener will listen for incoming TCP connections.

Here is my idea:

First we need an instance of StreamSocketListener.

private StreamSocketListener _listener = new StreamSocketListener(); 

Then start the listener, attach the connection handler, and bind the service name.

 _listener.ConnectionReceived += listenerConnectionReceived; await _listener.BindServiceNameAsync("localServiceName"); 

If the localServiceName parameter is an empty string, the system will select the local TCP port to which it will bind. MSDN

Now we need to restore the connection:

  void listenerConnectionReceived(StreamSocketListener sender, StreamSocketListenerConnectionReceivedEventArgs args) { Console.WriteLine(string.Format("Recive connection from {0}", args.Socket.Information.RemoteHostName.DisplayName)); }

BTW: I did a lot of research for this and did not have time (and the Windows 8 METRO Development Environment) to talk about my ideas. I hope I get to that soon. It bothers me a lot. (German / English);)
