title: Update live tile count and add +1 to count every time the Live Tile is updated
body: <p>I have this little code here that is executed in my <code>ScheduledTaskAgent</code> of my Windows Phone app, if this code is executed then there is some data to show. </p>
  
  <p>I have made an comparison before this code and I executes only if there is new data.</p>
  
  <p>Now I have no clue how to add each time the live tile update +1 (one) int to the Count of the <code>FlipTile</code> I use. this is my code:</p>
  
  <pre><code>ShellTile appTile = ShellTile.ActiveTiles.First();
                          if (appTile != null)
                          {
                              FlipTileData TileData = new FlipTileData()
                              {
                                  Title = "",
                                  BackTitle = "my App",
                                  BackContent = title.Collection.ElementAt(0).Title.ToString(),
                                  WideBackContent = title.Collection.ElementAt(0).Title.ToString(),
                                  Count =  ,     //?????
                              };
  
  
                              appTile.Update(TileData);
  </code></pre>
  
  <p>How can I make the count every time counts one more if this code is executed? </p>
  
  <p>I have really no clue. I tried with +1 but its an int and it doesnt give this +1 to the next live tile update so the count should be 2. </p>
  
  <p>I must say that <code>ScheduledTaskAgent</code> finishes its work and then a new instance of it is called, so I think the value that was first called in count must be saved, then at the next call retrieved and added to it +1. but how?</p>
