## What it is
Lidgren.Network is a C# networking library for the .NET framework that uses a single UDP socket to provide a simple client-server messaging API. This fork is updated for Unity3D compatibility but is no longer actively developed, accepting only minor bug fixes.

## Use cases
- add multiplayer networking to a Unity game
- send UDP messages between a C# client and server
- build a real-time game server in .NET
- implement reliable messaging over UDP in C#
- connect game clients to a server with a simple networking API

## When to choose
- you need a lightweight, proven UDP networking layer for a .NET or Unity game
- you want a simple client-server message API without heavy dependencies
- you're maintaining an existing project already built on Lidgren

## When to avoid
- you need a library under active development with ongoing support
- you require .NET Core / modern .NET official support
- you need TCP, WebSockets, or higher-level features like matchmaking or relay services

## Facets
- artifact type: library
- maturity: maintenance
- function: networking, p2p
- domain: networking
- platform: windows, cross-platform, dotnet
- tags: udp, game-networking, unity, csharp, client-server, game-development, real-time, linux, macos
