Message Queues are a great tool for interprocess communication if you need to ensure that a message is processed, regardless of the target process’s connectivity or runtime state. If you are developing with Microsoft’s .Net Framework you can take advantage of Windows Communication Foundations built-in support for Microsoft Message Queues. I have been using WCF with Microsoft Message Queues on a recent project, which as part of a back-end processor, the queues are automatically created in the event that they do not exist. The queues can be programmatically created using the following code (C#):
When you deploy this application to a Windows Server 2008 machine, the queue will be created as expected and as default allow messages to be inserted into the queue. However Windows Server 2008 R2 behaves a little differently, as default the queue will not allow anyone other than the owner to insert messages into the queue.
