title: Why we need Transient Fault Handling for storage?
body: <p>I saw some thread said storage library already have retry policy, 
  So why should us use this :<a href="http://msdn.microsoft.com/en-us/library/hh680905%28v=pandp.50%29.aspx" rel="nofollow">Transient Fault Handling block</a></p>
  
  <p>Can any one show me some samples about how to use this Transient Fault handling block for myy blob and Table storage properly? 
  thanks!</p>
