Implement messaging patterns

Your service needs to let clients open a channel to it and allow back and forth communication throughout the session. Which is true? (Choose all that apply)

As long as the service can stream back to the client, this would work.
Any binding that supports streaming would be a work here.
Duplex communication cannot be implemented with Http because it’s a stateful protocol.
Only bindings with the IsOneWay property set to true would be valid.
