How to read and send data to client from server?

I'm trying to make a server client using a local console server on my pc and a client on windows phone 8.1. The problem that I have is that I don't know how to read the incoming data from the client. I've searched the internet and read serveral microsoft tutorials but they do not explain how to read the incoming data in the server. Here's what I have.

Client on windows phone 8.1:

private async void tryConnect()
{
    if (connected)
    {
        StatusLabel.Text = "Already connected";
        return;
    }
    try
    {
        // serverHostnameString = "127.0.0.1"
        // serverPort = "1330"
        StatusLabel.Text = "Trying to connect ...";
        serverHost = new HostName(serverHostnameString);
        // Try to connect to the 
        await clientSocket.ConnectAsync(serverHost, serverPort);
        connected = true;
        StatusLabel.Text = "Connection established" + Environment.NewLine;
    }
    catch (Exception exception)
    {
        // If this is an unknown status, 
        // it means that the error is fatal and retry will likely fail.
        if (SocketError.GetStatus(exception.HResult) == SocketErrorStatus.Unknown)
        {
            throw;
        }
        StatusLabel.Text = "Connect failed with error: " + exception.Message;
        // Could retry the connection, but for this simple example
        // just close the socket.

        closing = true;
        // the Close method is mapped to the C# Dispose
        clientSocket.Dispose();
        clientSocket = null;
    }
}

private async void sendData(string data)
{
    if (!connected)
    {
        StatusLabel.Text = "Must be connected to send!";
        return;
    }
    UInt32 len = 0; // Gets the UTF-8 string length.

    try
    {
        StatusLabel.Text = "Trying to send data ...";

        // add a newline to the text to send
        string sendData = "jo";
        DataWriter writer = new DataWriter(clientSocket.OutputStream);
        len = writer.MeasureString(sendData); // Gets the UTF-8 string length.

        // Call StoreAsync method to store the data to a backing stream
        await writer.StoreAsync();

        StatusLabel.Text = "Data was sent" + Environment.NewLine;

        // detach the stream and close it
        writer.DetachStream();
        writer.Dispose();
    }
    catch (Exception exception)
    {
        // If this is an unknown status, 
        // it means that the error is fatal and retry will likely fail.
        if (SocketError.GetStatus(exception.HResult) == SocketErrorStatus.Unknown)
        {
            throw;
        }

        StatusLabel.Text = "Send data or receive failed with error: " + exception.Message;
        // Could retry the connection, but for this simple example
        // just close the socket.

        closing = true;
        clientSocket.Dispose();
        clientSocket = null;
        connected = false;

    }
}

And the server:

public class Server
{
    private TcpClient incomingClient;

    public Server()
    {
        TcpListener listener = new TcpListener(IPAddress.Parse("127.0.0.1"), 1330);
        listener.Start();

        Console.WriteLine("Waiting for connection...");
        while (true)
        {
            //AcceptTcpClient waits for a connection from the client
            incomingClient = listener.AcceptTcpClient();

            //start a new thread to handle this connection so we can go back to waiting for another client
            Thread thread = new Thread(HandleClientThread);
            thread.IsBackground = true;
            thread.Start(incomingClient);
        }
    }

    private void HandleClientThread(object obj)
    {
        TcpClient client = obj as TcpClient;

        Console.WriteLine("Connection found!");
        while (true)
        {
            //how to read and send data back?
        }
    }
}

It comes to the point where the server prints 'Connection found!', but I don't know how to go further.

Any help is appreciated!

EDIT:

Now my handleclientthread method looks like this:

private void HandleClientThread(object obj)
{
    TcpClient client = obj as TcpClient;
    netStream = client.GetStream();
    byte[] rcvBuffer = new byte[500]; // Receive buffer
    int bytesRcvd; // Received byte count
    int totalBytesEchoed = 0;
    Console.WriteLine("Connection found!");
    while (true)
    {
        while ((bytesRcvd = netStream.Read(rcvBuffer, 0, rcvBuffer.Length)) > 0)
            {
                netStream.Write(rcvBuffer, 0, bytesRcvd);
                totalBytesEchoed += bytesRcvd;
            }
            Console.WriteLine(totalBytesEchoed);
    }
}

But it still doesn't write the bytes to the console
