    Hi Jennifer, 


    I am confused why Duplex is described as a communication pattern for WCF, yet to implement requires the code to set up key pieces such as Context. I would have thought that the framework would encapsulate this so that newbies like me would not have to deal with it.


    Have I missed something about binding/channels that defines/establishes a servce as duplex?
