Is this possible? trying to look for examples that show a message being published by the server and having multiple clients subscribed to those messages
Technically, you could probably build a message transport over WCF with the NetTcpBinding, but you really don't want to. I wouldn't want to try.
It would be very difficult to replicate transactional message sending, store-and-forward, and the receive once and only once semantics that is baked right in to MSMQ.
