System.Net.Sockets.TcpClient find out client ip address?

Question

C++ / C#

Highly simplified code:

TcpListener listener = new TcpListener(IPAddress.Any, 30000);
listener.Start();
TcpClient client = listener.AcceptTcpClient();
Console.WriteLine(client.Client.RemoteEndPoint);
listener.Stop();
Console.ReadLine();

Stably returns 0.0.0.0:0, with AcceptSocket the situation is the same, while the bytes run, everything else works.
A very roughly equivalent Python code works fine:

import SocketServer

class MyTCPHandler(SocketServer.BaseRequestHandler):

    def handle(self):
        print self.client_address[0]

if __name__ == "__main__":
    HOST, PORT = "0.0.0.0", 30000
    server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler)
    server.serve_forever()
