MassTransit includes an endpoint name formatter (IEndpointNameFormatter) which can be used to automatically format endpoint names based upon the consumer, saga, or activity name. If you have any questions, please contact me(. When using ConfigureConsumer, the EndpointName, PrefetchCount, and Temporary properties of the consumer definition are not used.

If the retry is not configured, the message will be delivered to the failure queue If the Task method is abnormal, the message will trigger a retry.When the method is completed, the message is ack and removed from the queue Other consumers can't receive this message while the method is executing. The consumption method is a method that is waiting.Masstransit makes it easy to create applications and services that take advantage of message based, loosely coupled asynchronous communication to achieve higher availability, reliability and scalability. Embrace the Hollywood principle, which states, "don't call us, we'll call you."

The types of consumers include: general consumer, saga, saga state machine, routing activity (distributed tracking), processor handlers, job comsumers All the information to get MassTransit setup is out there but it is spread across the documentation, GitHub issues, StackOverflow and all the other usual places. Sorry for not attaching a unit test, I know that would have been useful, hopefully the bug report was enough ) It took me a while to work out what was going on, its a pretty corner case.
At the same time, since a consumer factory is used to create consumers, it also limits the number of concurrent consumers that exist at the same time. My application already uses AutoFac as a DI container, that I will take advantage of in this post. Concurrency Limit By specifying a concurrent message limit, MassTransit limits the number of messages delivered to a consumer at the same time. In MassTransit, a consumer can consume one or more messages In this post, I want to set up MassTransit with RabbitMq and.
