I recently ran across a problem wherein I was unable to add multiple Listen rules for my applications to my Topics in Azure Service Bus within an Azure Resource Group Template. I would run my template and it would fail to create the keys for the Topic or the Subscription for the topic of there was more than one of either of those for the Topic. It wouldn't even be consistent: it would switch back and forth between them between runs of the template. After a discussion with one of the Solution Architects at Microsoft, I found out there is, at the time of this writing, a bug in the Azure Resource Manager for Topics within Service Buses that prevents Topic access rules and subscriptions from being simultaneously created. As a work around, I was instructed to introduce an artificial dependency between each of the subscriptions to force the resource manager to create them serially rather than in parallel and this did the trick.
