SocketJack 2026.0.0

SocketJack

SocketJack is a batteries-included .NET networking stack for typed object transport, HTTP/WebSocket apps, mutable protocol hosting, streaming, peer routing, and WPF control sharing.

It handles framing, segmentation, serialization, compression, routing, protocol detection, TLS, static file hosting, stream routes, and callback dispatch so application code can focus on intent instead of wire plumbing.

Packages

Companion runtime projects are documented separately, including LlmRuntime/README.md.

Feature Map

Quick Start

Install the core networking package:

dotnet add package SocketJack

Or with Package Manager:

Install-Package SocketJack

Install WPF remoting when you need live WPF capture/input:

dotnet add package SocketJack.WPF

TCP

using SocketJack.Net;

var server = new TcpServer(port: 12345);
server.Listen();

server.RegisterCallback<ChatMessage>(args =>
{
    Console.WriteLine(args.Object.Text);
    args.Connection.Send(new ChatMessage("received"));
});

var client = new TcpClient();
await client.Connect("127.0.0.1", 12345);
client.Send(new ChatMessage("hello"));

public sealed record ChatMessage(string Text);

HTTP

using SocketJack.Net;

var server = new HttpServer(port: 8080);

server.Map("GET", "/health", (connection, request, ct) =>
{
    return new { status = "ok" };
});

server.MapDirectory("/static", @"C:\wwwroot");
server.Listen();

WebSocket

using SocketJack.Net;

var server = new WebSocketServer(port: 9000);
server.Listen();

server.RegisterCallback<ChatMessage>(args =>
{
    server.SendBroadcast(new ChatMessage(args.Object.Text));
});

var client = new WebSocketClient();
await client.Connect("127.0.0.1", 9000);
client.Send(new ChatMessage("hello from websocket"));

MutableTcpServer

MutableTcpServer lets HTTP, SocketJack, WebSocket, RTMP, and custom protocols share one listening port.

using SocketJack.Net;

var server = new MutableTcpServer(port: 9000);

server.Http.Map("GET", "/status", (connection, request, ct) => "ok");
server.WebSocketClientConnected += connection => Console.WriteLine($"WebSocket: {connection.ID}");
server.SocketJackClientConnected += connection => Console.WriteLine($"SocketJack: {connection.ID}");

server.Listen();

WPF Remoting

Install SocketJack.WPF, then share any WPF element over a SocketJack connection.

using SocketJack.WPF;

IDisposable shareHandle = GameCanvas.Share(client, remotePeer, fps: 10);
