2. B. Create an interface for the client-side duplex contract.
3. C. Create an interface for the server-side duplex contract.
4. D. Apply the MessageContractAttribute attribute to the appropriate interface.
5. E. Apply the ServiceContractAttribute attribute to the appropriate interfac
6. F. Then, apply the OperationContractAttribute attribute to every public method signature included in that contract.
7. G. Set the CallbackContract property to the appropriate interface.

Correct Answer: CEF
To create a duplex contract
(C) Create the interface that makes up the server side of the duplex contract.
(E) Apply the ServiceContractAttribute class to the interface.
Declare the method signatures in the interface.
(E) Apply the OperationContractAttribute class to each method signature that must be part of the public contract.
Create the callback interface that defines the set of operations that the service can invoke on the client.
Declare the method signatures in the callback interface.
Apply the OperationContractAttribute class to each method signature that must be part of the public contract.
(F) Link the two interfaces into a duplex contract by setting the CallbackContract property in the primary interface to the type of the callback interface.
