Embed external application in wpf application

Hello, i want embed a game in my wpf application. The game is a turn by turn mmorpg, most people play 8 account (8 client...) It's not easy to navigate with 8 client in windows. ALT+ESC... I want create an application where I can put a navigation bar with tabs at the top and each tab represents 1 client. I search and test many options but none works. I'm sure is possible because one application exist, but i want create mine for share in open source project (app already exist have very bad UI and not open source) Thank you very much !

✅ Socket not Listen

Hello when i call OnClientConnected() my console close. Yet, my socket listens well for 100 sec, but the console not wait my client connexion You have an idea ? Thanks you !

class Program
{
    static IPAddress ipAddress = IPAddress.Parse("127.0.0.1");
    static IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 5555);
    static private Socket listener = new Socket(ipEndPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

    static void Main(string[] args)
    {
        StartupServer();
        OnClientConnected();
    }

    private static void StartupServer()
    {
        // Ecoute du serveur
        listener.Bind(ipEndPoint);
-       listener.Listen(100);
        Console.WriteLine("Serveur démarré, en attente du client...");
    }

    private static async void OnClientConnected()
    {
        // Connexion du client
-       await listener.AcceptAsync();
        Console.WriteLine($"Client : \"{ipAddress.MapToIPv4()}\" sur le port : \"{ipEndPoint.Port}\" connecté au serveur.");
    }

class Program
{
    static IPAddress ipAddress = IPAddress.Parse("127.0.0.1");
    static IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 5555);
    static private Socket listener = new Socket(ipEndPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

✅ Unable to read beyond the end of the stream.

Hello, i have error : Unable to read beyond the end of the stream. at line "short hiheader = reader.ReadInt16();" do you know for what ? thanks

IPAddress ipAddress = IPAddress.Parse("127.0.0.1");
IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 5555);

using Socket listener = new Socket(ipEndPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

listener.Bind(ipEndPoint);
listener.Listen(100);
Console.WriteLine("Serveur démarré, en attente du client...");

var handler = await listener.AcceptAsync(); // Connexion du client
Console.WriteLine($"Client : \"{ipAddress.MapToIPv4()}\" sur le port : \"{ipEndPoint.Port}\" connecté au serveur.");


MemoryStream memoryStream = new MemoryStream();
var buffer = new byte[1024];

while (true)
{
    int byteReceived = await handler.ReceiveAsync(buffer, SocketFlags.None);

    if(byteReceived > 0)
    {
        memoryStream.Write(buffer, 0, byteReceived);
    }
    else
    {
        break;
    }

    BinaryReader reader = new BinaryReader(memoryStream);

-    short hiheader = reader.ReadInt16(); // HiHeader (2octets) = packetId (8bits) + lenType (6bits)
    short packetId = ((short)(hiheader >> 2)); 
    short lenType = ((short)(hiheader & 3));

✅ Dynamic Buffer

Hello ! I want create a dynamic buffer and i didnt know how to proced. I want Receive bytes of my client, and stock only the bytes receive. Actualy use :

byte buffer = new byte[1024]
var received = await handler.ReceiveAsync(buffer, SocketFlags.None)

byte buffer = new byte[1024]
var received = await handler.ReceiveAsync(buffer, SocketFlags.None)

problem is i use lot of memory unnecessarily if receive little packet Thanks for your help, Slycex. PS : sorry for my english :S
