Is your feature request related to a problem? Please describe.

I created an RPC client based on the C# RPC tutorial, and was burned by the queue declaration approach when one of our nodes went offline. All our services using the RPC client were still online, but they were not receiving replies to requests, which sadly made them useless.

Describe the solution you'd like

I would like the RPC tutorial(s) to utilize the Direct Reply-to feature in RMQ that solves this issue entirely.

Describe alternatives you've considered

An alternative could be to mention that using a server-named queue does not work well in the scenario that a node fails, when using a RMQ cluster.
