This blog is part of a series exploring RabbitMQ and MassTransit. Previous episodes are available at
In the last episode I did a lot of handwaving over the mess I made of configuration. There were hard coded values all over the place. In this article we’ll clear up some of the mess we made.
In the last post, we created an application which can send tasks to a background processor. We did it directly with RabbitMQ which was a bit of a pain. We had to do our own wiring and even our own serialization. Nobody wants to do that for any sort of sizable application. Wiring would be very painful on a large scale.
There are a couple of good options in the .NET space which can be layered on top of raw queues. NServiceBus is perhaps the most well know option. There is, of course, a cost to running NServiceBus as it is a commercial product. In my mind the cost of NServiceBus is well worth it for small and medium installations. For large installations I’d recommend building more tightly on top of cloud based transports, but that’s a topic for another blog post.
In the last post we looked at how to set up RabbitMQ in a Windows container. It was quite the adventure and I’m sure it was woth the time I invested. Probably. Now we have it set up we can get to writing an application using it.
A pretty common use case when building a web application is that we want to do some background processing which takes longer than we’d like to keep a request open for. Doing so would lock up an IIS thread too, which ins’t optimal. In this example we’d like to make our user creation a background process.
