What is Microsoft Message Queuing (MSMQ)? How does it work?

Question

I need to work with MSMQ (Microsoft Message Queuing). What is it, what is it for, how does it work? How is it different from web services?

Answer 1

As its name states, it's just a queue manager.

You can Send objects (serialized) to the queue where they will stay until you Receive them. It's normally used to send messages or objects between applications in a decoupled way

It has nothing to do with webservices, they are two different things
