Bruce Williams illustrates how to turn my very simple “Hello World” Indigo sample into a queued service by changing the transport binding from HTTP to MSMQ (I think that’s radically cool). Now, the next step is to illustrate a Duplex conversation to get the response back to the caller. If Bruce or someone else isn’t going to beat me to it, I’ll show that once I get home from Warsaw tomorrow night. [Ah, by the way: Bruce! No need to “Mr.” me ]
