NServiceBus v3 does not automatically create queues
Queues are not automatically created anymore since NServiceBus v3. Queues are now created during the installation phase which you usually do not have in web apps or test apps. You can still have the old behavior by triggering the installation during bus creation. Make the following change to trigger this.
// From:
.Start()
// To:
.Start(() => Configure.Instance.ForInstallationOn<Windows>().Install());
