Container.CreateIfNotExist throws exception if container exists

We are trying to create a container reference with the new 1.7.1 SDK but when the container exists it will throw an exception:

 //Get a reference to the container for which shared access signature will be created.  
 CloudBlobContainer container = blobClient.GetContainerReference(containerName);

 // create the container if not exists
 container.CreateIfNotExist();

This is the exception:

Microsoft.WindowsAzure.StorageClient.StorageClientException was unhandled by user code
  Message=The specified container already exists.

It’s ridiculous that there’s a method named CreateIfNotExists that is supposed to throw if the container already exists. – That’s what the regular Create should do. – additionally, the exception that comes back has the IsRetryable boolean set to true – even though, no matter how many retries you do, it will never succeed. 😦

2.5 years later and they still have this bug. Just wow…
