What additional components or tools does MassTransit use besides working with message brokers?

MassTransit is a library for working with messages in .NET that simplifies interaction with message brokers (e.g., RabbitMQ, Azure Service Bus). Besides basic broker interaction, MassTransit provides a number of additional components and tools:

• Middleware — allows injecting additional logic into the message processing pipeline (e.g., logging, retries, filtering).
• Sagas — a mechanism for managing long-running business processes and coordinating multiple messages and states.
• Configuration and routing — convenient APIs for setting up message routes and subscribers.
• Integration with DI containers — support for popular dependency injection containers.
• Monitoring and tracing — integration with tools for tracking status and performance.

These components make MassTransit a powerful tool for building distributed systems and microservices.
