Get CloudQueueMessage in Windows Azure worker role throws IO Exception in Azure Emulator

Question

As can be seen from the image below I'm doing a pretty standard bit of code in a Worker Role to get a message from a queue in Azure Storage but it's throwing this IOException with text saying the specified registry key does not exist .

    CloudQueueMessage message = queue.GetMessage(TimeSpan.FromSeconds(30));

is the code that's causing the problem, sometimes it works fine or other times it doesn't. Very strange.

Have you set your Local Config file Connection String to use UseDevelopmentStorage=true

From a quick google, this error can crop up as well if you have a mis-match between the Microsoft.WindowsAzure.StorageClient (v1.7) and the Microsoft.WindowsAzure.Storage (v2.0) libraries referenced in your application.
