I know I am late, but just trying to add my points; this may help someone else on the same subject.

I used MassTransit, which is a free-to-use library, and I have been using it for 5 years in production.

It supports Azure Service Bus cohesively and provides a duplex messaging with support of both DeadLetter and Error queue.

TIP: Write the consumer/subscriber on the Interfaces of the model if you are using MassTransists.
