Xport

A lightweight, Kestrel-inspired transport server for .NET.

Features

• Multiple Transports — TCP sockets, Unix domain sockets, QUIC, and Named Pipes (Windows only)
• Middleware Pipeline — Compose connection handlers with the same middleware pattern used in ASP.NET Core
• Hosted Service Integration — Runs as an IHostedService alongside your existing .NET applications
• Connection Management — Built-in connection limiting with pluggable rate-limiting policies
• AOT Compatible — Supports native ahead-of-time compilation
• Modern .NET — Targets .NET 6 through .NET 10

        // Do something after
    }
}
