I've started looking at MassTransit and am writing the classes that will handle the messages. When I implement the interface from Consumes<T> I get four options: All, Selected, For<T> and Context. What is the difference between the four and when should them be used?

有帮助吗?

All just gives you all the messages to consume. Context is All but you also get the Context<TMessage> if you need it. Selected allows you to accept or reject messages before it gets to your consumer. For<T> is primarily for Sagas, I don't think there's a good use case for it outside of that.

Starting off, just using All is likely the right answer.
