title: MassTransit RequestResponse sample move responses to skipped queue on .Net core
body: <p>I ported MassTransit <a href="https://github.com/MassTransit/Sample-RequestResponse" rel="nofollow noreferrer">Sample-RequestResponse sample</a> to .net core. Did some small modifications to the sample in order to host the .net core service. Although the service can receive the requests, the response is not received by the client and end up in ignore_skipped queue on rabbitmq. However, in some executions I receive a response to the first request I sent, and fails there after. What is the root cause for this? How can we implement RequestResponse pattern on MassTransit</p>
