TL;DR
MassTransit is the de-facto .NET abstraction over RabbitMQ. It gives you type-safe contracts, declarative topology (exchanges/queues/bindings auto-declared on startup), consumers as classes, sagas (state machines for long-running workflows), the outbox pattern (transactional consistency with EF Core), retry/redelivery policies, and scheduled messages — all without writing AMQP plumbing. "Migrations" for messaging = topology evolution and message-format versioning. Topology is declarative and applied on startup (analog of MigrateAsync); message-format changes are managed via versioned contracts or schema registries.
