I've been looking into Azure Service Bus Queues (NOT Azure Storage Queues). All of the details that I have read indicate that it supports FIFO semantics, but only in the context of a "Messaging Session". The problem is that I can't seem to find any information on what exactly this is in the context of Azure. Is this a WCF construct, or something that is particular to Azure Service Bus? I assume that it does not relate to local transactions, but I am not 100% sure.

Any pointers would be very helpful. Thanks!

Specifically it refers to MessageSession, and it's the AcceptMessageSession method that holds the key by returning messages only for a given session id, which could be a sequence implying some ordering. The Brokered Messaging: Session Messages sample should help clarify, and the Best Practices document is another great reference.
