title: Azure table storage error: "Unexpected response code for operation : 99"
body: <p>I got this error when I executed the following code:</p>
  
  <pre><code>var insert = new TableBatchOperation();
  foreach (var entity in entities)
  {
      insert.Insert(entity);
  }
  cloudTable.ExecuteBatch(insert);  
  </code></pre>
  
  <p>Where the entities collection contained 512 elements.
  The Azure SDK through a StorageException:</p>
  
  <pre><code>"Unexpected response code for operation : 99" 
  </code></pre>
  
  <p>What does this error mean, and how can I solve this?</p>
