With MSMQ we went from a complex synchronous workflow to a simple and fast order placement workflow. This new workflow asynchronously spawned a variety of secondary workflows by having the primary order placement workflow post a message in the transactional queue of each of the isolated processors for steps Since these queues were transactional we knew that each message would get processed and we could also build in retry mechanisms when failures occurred, especially with third parties like mail servers and credit card processors.

In terms we use today, we went from a tightly coupled system to a very loosely coupled, scalable set of services that were involved in processing an order. If any one of these processes e. We refer to this as having many knobs and dials to be able to turn as opposed to one big knob. We have a single sender and a single listener. The sender and the listener must both listen to the same queue.

We use private queues and not public queues since the queuing occurs on a single machine. The code below creates or opens an MSMQ object. When creating a new queue, you will usually make it transactional. Transactional queues allow for commit and rollback operations, which are essential for preventing data loss. Note the MessageQueue object. It is a disposable object. Normally when creating any IDisposable object I like to wrap it in a using statement. But in the code above we are not doing that.

That is an intentional omission because we will be wrapping the result of GetQueueReference in a using statement. This small touch within the UX provides great simplicity.

The other aspect is the queue to restore itself on server reboot. Unfortunately despite providing those parameters, our data is being lost. We have somehow enabled a edge case bug.

I would recommend moving to a different queueing platform as soon as reasonable. Almost everyone I talked to while researching this recommended RabbitMQ as the default choice. MSMQ and.

In his article titled MSMQ is dead , David Boike cites two major advantages of MSMQ that need to be considered when trying to switch to a different message queueing system: MSMQ is a distributed or federated messaging system where every server hosts the queue infrastructure, and outgoing messages are sent locally before being delivered to their ultimate address.
