title: Adding Multiple PushPin to Bing Map control (XAML & C#) in WINRT
body: <p>How i can add  multiple push pins to bing map control. In my application, i tried to add some user control(Push pins) as children of that map control. But the issue is that when i performing zoom -in and zoom-out operation the push pin moves around the map and miss places the position.
  Here is the code i used for adding multiple push pins to the map :</p>
  
  <pre><code>            foreach (var item in PushPinCollection)
              {
                      var pin = new CustomMapPin(Convert.ToInt32(item.BackgroundColorID)) { Name = item.ID.ToString() };
                      pin.DoubleTapped += PushpinTapped1;
                       pin.Tapped += PinTapped;
                       var loc = new Location(Convert.ToDouble(item.Latitude, System.Globalization.CultureInfo.InvariantCulture), Convert.ToDouble(item.Longitude, System.Globalization.CultureInfo.InvariantCulture));
                       pin.SetValue(MapLayer.PositionProperty, loc);
                       NoteMap.Children.Add(pin);
                  }
  </code></pre>
