Transactional Outbox Sample

This sample shows how to configure and use MassTransit's new transactional outbox, including:

• An API controller that uses a domain registration service to register a member for an event. The controller has no knowledge of MassTransit, and the registration service uses IPublishEndpoint to publish a domain event which is written to the transactional outbox.
• Adds the transactional outbox delivery service as a hosted service, which delivers outbox message to the transport.
• A separate service that consumes the domain event by itself, and also includes a saga state machine which uses the transactional outbox (and inbox, for idempotent message delivery).
