All the examples I find about Service Bus Queues are in the scenario where the web role sends the message and there's a dedicated worker role receiving the messages.
Mi situation is different. The worker role is the one that generates the messages and must be received by the web role.
I guess that the RoleEntryPoint of the webrole should have an infinite while that listens for new messages, but the messages received must be processed by components in my webrole and as far as I know the RoleEntryPoint is not accesible from the web app.
Any Ideas?
