Typenkonventierung Fehlermeldung

Hallo zusammen.
Ich habe auf der MSDN Seite einen TCP Server gefunden
http://msdn.microsoft.com/de-de/library/system.net.sockets.tcplistener.accepttcpclient(v=vs.90).aspx
und wollte diesen kompilieren.
Doch ich erhalte die Fehlermeldung

Cannot implicitly convert type System.Net.Sockets.TcpClient to System.Net.Sockets.Socket

Ich glaube der mag das AcceptTcpClient( ) nicht kann mir da einer weiterhelfen?

using System;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Threading;

public class TcpListenerSample
{

    static void Main(string[] args)
    {
        try
        {
            // set the TcpListener on port 13000
            int port = 13000;
            TcpListener server = new TcpListener(IPAddress.Any, port);

            // Start listening for client requests
            server.Start();

            // Buffer for reading data
            byte[] bytes = new byte[1024];
            string data;

            //Enter the listening loop
            while (true)
            {
                Console.Write("Waiting for a connection... ");

                // Perform a blocking call to accept requests.
                // You could also user server.AcceptSocket() here.
                TcpClient client = server.AcceptTcpClient();
                Console.WriteLine("Connected!");

                // Get a stream object for reading and writing
                NetworkStream stream = client.GetStream();

                int i;

                // Loop to receive all the data sent by the client.
                i = stream.Read(bytes, 0, bytes.Length);

                while (i != 0)
                {
                    // Translate data bytes to a ASCII string.
                    data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
                    Console.WriteLine(String.Format("Received: {0}", data));

                    // Process the data sent by the client.
                    data = data.ToUpper();

                    byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);

                    // Send back a response.
                    stream.Write(msg, 0, msg.Length);
                    Console.WriteLine(String.Format("Sent: {0}", data));

                    i = stream.Read(bytes, 0, bytes.Length);

                }

                // Shutdown and end connection
                client.Close();
            }
        }
        catch (SocketException e)
        {
            Console.WriteLine("SocketException: {0}", e);
        }

        Console.WriteLine("Hit enter to continue...");
        Console.Read();
    }

}

Keine Ahnung was du gemacht hast, aber der Code aus der MSDN laeuft bei mir Einwandfrei.
