//Difference in this example is that no metadata is required by the client, as the client has access to the
//contract assembly.Instead of generating a proxy class from metadata, the client obtains the refence to the
//service contract interface through an alternative method. Another point to note about this example is the
//use of a session to maintain state in the servie, which requires the WSHttpBinding binding istead of the
//BasicHttpBinding binding

//The client application has no app.config file to configue the communications with the service and no proxy class defined from metadata
//to communicate with the service. Instead a proxy class is created through the ChannelFactory<T>.CreateChannel() method. This method
//creates a proxy class that implements the IAwardService client, although behind the scenes, the generated class communicates with the
//service just like the metadata-generated proxy shown earlier. Note if you create a porxy class with ChannelFactory<T>.CreateChannel(),
//the communication channel will, by default, time out after a minute, which can lead to communication errors. There are ways to keep
//connections alive, but they are beyond the scope of this chapter. Creating proxy classes this way is extremely useful technique that you
//can use to quickly generate a client application on the fly.
