description	Local MassTransit documentation reference (latest). MassTransit message bus documentation. Use for distributed messaging, consumers, sagas, state machines, RabbitMQ, Azure Service Bus, Amazon SQS, and event-driven architecture in .NET.

MassTransit Documentation

MassTransit is an open-source distributed application framework for .NET that provides a consistent abstraction on top of supported message transports (RabbitMQ, Azure Service Bus, Amazon SQS, Kafka, ActiveMQ, SQL, and more). It simplifies building event-driven, message-based applications with consumers, sagas, state machines, routing slips, and the outbox pattern.

When to use

Use this skill when the user asks about:

• Setting up MassTransit with any transport (RabbitMQ, Azure Service Bus, Amazon SQS, Kafka, SQL)
• Defining and consuming messages in .NET
• Publishing and sending messages, request/response patterns
• Writing consumers, including fault consumers and exception handling
• Sagas, state machines, and stateful workflow patterns
• Saga persistence with Entity Framework, MongoDB, Redis, Marten, DynamoDB, etc.
• Outbox pattern (in-memory or transactional) for exactly-once delivery
• Routing slips and activity-based workflows (Courier)
• Job consumers for long-running background work
• Middleware, filters, and pipeline customization
• Message scheduling and delayed delivery
• Topology configuration and broker setup
• Testing MassTransit applications with the test harness
• Observability with OpenTelemetry
• Upgrading MassTransit versions
