  <p>This above exception occurs randomly and not able to get/reproduce it every time.</p>
  
  <p>I know that the error would seem to indicate that this is a transient connection issue between Azure and SQL. However, I have configured the data context to use the SqlAzureExecutionStrategy which should be handling dropped connections.</p>
