title: How to upload a folder to Azure storage
body: <p>I would like to upload an entire folder to azure storage.
  I know I can upload a file using:</p>
  
  <pre><code>blobReference.UploadFromFile(fileName);
  </code></pre>
  
  <p>But could not find a method to upload an entire folder (recursively).
  Is there such method? Or maybe an example code?</p>
  
  <p>Thanks</p>
