silent WebException when using blob storage account kind.

[Bartmax]

I used this extension with a Blob storage account kind.

Everything worked fine when I installed it, but today I discovered that logs shows that the extension is run very often and fails with

Unhandled Exception: Microsoft.WindowsAzure.Storage.StorageException: 
The remote name could not be resolved: 'xxx.queue.core.windows.net' ---> 
System.Net.WebException: The remote name could not be resolved: 'xxx.queue.core.windows.net'

1. is it possible to make it work with blob storage only accounts? if not, it would be great to add to the doc/readme. Specially because it fails silently (unless you look around) and you cannot (or didn't find how) to change from one account kind to another.

2. How bad is my current scenario? What is queue used for?

The web jobs sdk uses queues internally. So yes it is required to use a general purpose storage account.
Azure/azure-webjobs-sdk#797
Will make it cleared in the documentation.

I created a WebJob without the WebJob SDK so no storage account of any kind is required:
