What is the main difference between request response and duplex in WCF message exchange pattern?
In Request-Response the service only communicates back after receiving a Request from the client. So by using duplex you receive an event-like behavior from the client perspective. Obviously such enhancement requires a Session to be maintained (instance mode PerSession on the service). You can read more on the msdn.
What is default message exchange pattern in WCF?
The default message exchange pattern is request-reply in WCF. The client only sends the request to the service and it will not wait for the response back from the service. The client will not get any exceptions if it is occurring during the service processing it, because the client is not waiting for the result here.
