title: How to get a CloudBlobDirectory pointing toward the container root?
body: <p>With the <a href="http://www.nuget.org/packages/WindowsAzure.Storage" rel="nofollow">WindowsAzure.Storage</a> library, I would like to create a <code>CloudBlobDirectory</code> that refers to the root of the container. The method <code>CloudBlobContainer.GetDirectoryReference(string)</code> unfortunately fails with an argument exception called with <code>String.Empty</code> as argument.</p>
  
  <p>Is-it possible to have a <code>CloudBlobDirectory</code> referring to the root of the container?</p>
