NetConduit

License: MIT

Transport-agnostic stream multiplexer for .NET. Run many independent virtual channels over a single bidirectional stream — TCP, WebSocket, UDP, IPC, or QUIC — with credit-based backpressure, priority queuing, keepalive, graceful shutdown, and automatic reconnection with replay.

Core NuGet Description
NetConduit NuGet Multiplexer, channels, framing, reconnection
Transits NuGet Description
NetConduit.Transit.Stream NuGet Simplex Stream over one channel
NetConduit.Transit.DuplexStream NuGet Bidirectional Stream over a channel pair
NetConduit.Transit.Message NuGet Length-prefixed typed JSON messages
NetConduit.Transit.DeltaMessage NuGet State sync via JSON deltas
Transports NuGet Description
NetConduit.Transport.Tcp NuGet TCP sockets
NetConduit.Transport.WebSocket NuGet WebSocket (ClientWebSocket + ASP.NET)
NetConduit.Transport.Udp NuGet UDP with a reliability shim
NetConduit.Transport.Ipc NuGet TCP loopback (Windows) / Unix domain sockets (Linux/macOS)
NetConduit.Transport.Quic NuGet QUIC over TLS 1.3

Each transport and transit package depends on NetConduit, so installing one pulls in the core.

One physical stream carries any number of independent virtual channels. Each channel has its own buffer, priority, and lifecycle.

Install

Pick one transport and any transits you need:

dotnet add package NetConduit.Transport.Tcp
dotnet add package NetConduit.Transit.Message

Target frameworks: net8.0, net9.0, net10.0. AOT-compatible.

Quick start

A TCP server and client exchanging typed JSON messages.

using System.Text.Json.Serialization;
using NetConduit;
using NetConduit.Models;
using NetConduit.Transit.Message;
using NetConduit.Transport.Tcp;

public record Hello(string Name, int Count);

[JsonSerializable(typeof(Hello))]
internal partial class AppJson : JsonSerializerContext;

// Server
using var listener = new System.Net.Sockets.TcpListener(System.Net.IPAddress.Loopback, 5000);
listener.Start();
await using var server = StreamMultiplexer.Create(TcpMultiplexer.CreateServerOptions(listener));
server.Start();
await server.WaitForReadyAsync();

await using var inbox = await server.AcceptMessageTransitAsync<Hello>("hello", AppJson.Default.Hello);
await foreach (var msg in inbox.ReceiveAllAsync())
    Console.WriteLine($"got: {msg!.Name} x{msg.Count}");

// Client
await using var client = StreamMultiplexer.Create(TcpMultiplexer.CreateOptions("127.0.0.1", 5000));
client.Start();
await client.WaitForReadyAsync();

await using var outbox = await client.OpenMessageTransitAsync<Hello>("hello", AppJson.Default.Hello);
await outbox.SendAsync(new Hello("Alice", 1));
await outbox.SendAsync(new Hello("Alice", 2));

That's it. The server can open additional channels for file transfers, control plane, state sync, etc. — all over the same TCP connection.

What you get

  • Many channels per stream. Open and accept named channels at will. Each is independently flow-controlled and prioritized.
  • Pluggable transport. Swap TCP for WebSocket, UDP, IPC, or QUIC by changing one factory call.
  • Transits. Optional layers that turn a channel pair into a Stream, a typed message queue, or a state-sync delta channel.
  • Backpressure. Per-channel slab buffers with credit-based flow control. Slow consumers slow down their producer without blocking other channels.
  • Priority queuing. Five priority levels (Lowest … Highest) control writer ordering when channels compete for the wire.
  • Heartbeats. Configurable ping/pong with a missed-ping threshold detects dead connections quickly.
  • Graceful shutdown. GoAwayAsync drains in-flight data before tearing down.
  • Reconnection with replay. When configured, the multiplexer rebuilds the connection on transport failure and replays buffered frames so open channels survive.
  • AOT and trim safe. Core uses no reflection. Message and delta transits accept source-generated JsonTypeInfo<T>.
