title: Determine how many changes pulled using Azure Mobile App Service?
body: <p>In my offline-sync Xamarin.Forms mobile app, I want to inform the user that new stuff is available for review. To do that I need to know when CHANGES are pulled via <code>PullAsync()</code>.</p>
  
  <p>I can do a <code>countRecordsAfterPull() - countRecordsBeforePull()</code> but that will only tell me the number of NEW records. I also need to know the number of UPDATED records. (And if some records were soft DELETED, they should not interfere with these counts.)</p>
  
  <p>And of course, I need references to all those records, so I can work with them.</p>
  
  <p><em>Can this be done?</em></p>
