## What it is
NetMQ is a 100% native C# port of the ZeroMQ lightweight messaging library for .NET. It provides asynchronous message-queue sockets supporting multiple messaging patterns, subscriptions, and multiple transport protocols.

## Use cases
- send messages between .NET services over tcp
- implement pub-sub messaging in C#
- build request-reply communication between processes
- replace heavyweight message brokers with lightweight sockets
- connect distributed .NET components with inproc or ipc transports

## When to choose
- you need ZeroMQ-style messaging in a .NET application without native dependencies
- you want lightweight messaging patterns like pub-sub, push-pull, or request-reply in C#
- you need asynchronous message queues across multiple transports

## When to avoid
- you need a full-featured message broker with persistence and clustering
- you are not working on the .NET platform
- you require guaranteed message delivery or transactions

## Facets
- artifact type: library
- maturity: active
- function: message-queue, networking, rpc, concurrency
- domain: microservices, developer-tools
- platform: dotnet, cross-platform, windows
- tags: zeromq, csharp, messaging-patterns, pub-sub, request-reply, sockets, messaging, linux, macos
