In this third and last part of the duplex story in Silverlight, we’ll take a look at the third option offered by Silverlight to perform duplex communication.
Let’s quickly review the first two options. In Part 1, we looked at the Http Polling Duplex binding. Using a continuous polling mechanism on the network layer, this binding makes it possible to create an illusion of duplex communication. The big plus of this binding is the possibility we have to use it in internet scenarios, since all communication goes over plain HTTP.
