I’m having 70-513 exam soon. There is a question in the dump that i don’t understand.
A WCF service implements a contract with one-way and request-reply operations. The service is exposed over a TCP transport. Client use a router to communicate with the service.
The answer said using IDuplexSessionRouter instead of IRequestReplyRouter. Can i know why cannot use IRequestReplyRouter??
That question is covered in this msdn article: Building a router (look for “Routers and Transport Sessions” section there)
