Hey folks!! Hope you can help me with my client code.
Först I debugg the Server which is an consoleapplication and the server starts, secondly I debugg the Client, I put a nickname value to the nickNameTextBox and click on Connect the compiler stops at this code line on the getMessage()

serverStream.Read(inStream, 0, buffSize);


The Client

using System.Windows.Forms;
using System.Net.Sockets;
using System.Threading;


namespace Client
{
    public partial class Form1 : Form
    {
        System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();
        NetworkStream serverStream = default(NetworkStream);
        string readData = null;


        public Form1()
        {
            InitializeComponent();
        }
        //Connect to the Server
        private void connectButton_Click(object sender, EventArgs e)
        {
            
                clientSocket.Connect("127.0.0.1", 8888);
                serverStream = clientSocket.GetStream();


                byte[] outStream = System.Text.Encoding.ASCII.GetBytes(nickNameTextBox.Text + "$");
                serverStream.Write(outStream, 0, outStream.Length);
                serverStream.Flush();
           
            //else
            //{
            //    MessageBox.Show("Connect to the server");
            //}

        }

        private void sendButton_Click(object sender, EventArgs e)
        {

            if (serverStream == null)
            {
                MessageBox.Show("Please connect to a server.");
                return;
            }
            else
            {

                readData = "Conected to Chat Server ...";
                msg();
                //clientSocket.Connect("127.0.0.1", 8888);
                serverStream = clientSocket.GetStream();

                byte[] outStream = System.Text.Encoding.ASCII.GetBytes(sendTextBox.Text + "$");
                serverStream.Write(outStream, 0, outStream.Length);
                serverStream.Flush();

                Thread ctThread = new Thread(getMessage);
                ctThread.Start();
            }


        }
        private void getMessage()
        {
            while (true)
            {
                serverStream = clientSocket.GetStream();
                int buffSize = 0;
                byte[] inStream = new byte[10025];
                buffSize = clientSocket.ReceiveBufferSize;
                serverStream.Read(inStream, 0, buffSize);
                string returndata = System.Text.Encoding.ASCII.GetString(inStream);
                readData = "" + returndata;
                msg();
            }
        }
        private void msg()
        {

            if (this.InvokeRequired)
            {
                this.Invoke(new MethodInvoker(msg));

            }
            else
            {
                loggTextBox.Text = loggTextBox.Text + Environment.NewLine + " >> " + readData;
            }
        }
