Queuing in WCF

While designing distributed applications, selecting a transport is fairly important. Factors that you should consider include the requirements of the client and the service but, most important, whether you need a direct transport or a more isolated transport. In other words, unlike a direct transport such as HTTP or TCP where all the communication will fail if the network goes down, you want more resilience in the transport to overcome this issue. Typically, using a queued transport will overcome this scenario, since it is backed by a store (that is, a durability container).

Out of the box WCF provides the ability to use MSMQ, which is the Microsoft implementation of queued transports at the operating system level. Queues store ...
