## What it is
Rebus is a lean, free service bus implementation for .NET that provides asynchronous messaging between services following the 'smart endpoints, dumb pipes' principle. It ships as a .NET Standard 2.0 library with minimal dependencies and integrates with transports and containers via small dedicated integration projects.

## Use cases
- send and receive messages between .NET microservices
- implement asynchronous communication in a service bus architecture
- decouple services with a message bus without heavy middleware
- build event-driven .NET applications with queues
- integrate messaging with an IoC container in .NET
- retry and handle message failures in distributed systems

## When to choose
- you are building .NET microservices that need lightweight asynchronous messaging
- you want a simple, low-dependency alternative to full enterprise service buses like NServiceBus or MassTransit
- you prefer configuring messaging in code with a small set of well-chosen options

## When to avoid
- your stack is not .NET-based
- you need a full-featured broker with built-in management UI and enterprise tooling out of the box
- you require zero external transport infrastructure

## Facets
- artifact type: library
- maturity: stable
- function: message-queue, rpc, middleware
- domain: microservices, backend
- platform: dotnet, c, cross-platform
- tags: service-bus, message-bus, asynchronous-messaging, smart-endpoints-dumb-pipes, csharp, messaging
