title: Parallel loop in winrt
body: <pre><code>for (int j = 0; j &lt; 10; j++)
  {
      for (long i = 0; i &lt; bound / 10; i++)
      {
          routeLine.Locations.Add(new Location
          {
              Latitude = ((BingMapsRESTService.Route)(r.ResourceSets[0].Resources[0])).RoutePath.Line.Coordinates[k][0],
              Longitude = ((BingMapsRESTService.Route)(r.ResourceSets[0].Resources[0])).RoutePath.Line.Coordinates[k][1]
          });
  
          k++;
      }
  
      await Task.Delay(TimeSpan.FromMilliseconds(1));
  
      Temp("Drawing Route (" + ((j * 10)/2).ToString() + "%)"); // to show progress,Temp sets text property of a textbox
  }
  </code></pre>
  
  <p>Bound has value between 6000 to 10000. This loop takes time and hang the UI that's why i divided the loop into 10 parts and used task.delay. 
  Is it possible to run all ten loops in parallel? I can't use thread as I can't create object of Location class in new thread. It throws an error of task being marshaled by some another thread</p>
