title: Binding to a Map in a universal app
body: <p>I'm working on a universal app, and for the Windows Store version, this wraps the Bing Maps control, based on code from <a href="http://blogs.msdn.com/b/rbrundritt/archive/2014/06/24/how-to-make-use-of-maps-in-universal-apps.aspx" rel="nofollow">Ricky Brunditt's blog</a></p>
  
  <p>For testing purposes, I've tried to add a pushpin via XAML, with:</p>
  
  <pre><code>&lt;Maps:MapControl ZoomLevel="14" MapServiceToken="{StaticResource MapServiceToken}" Width="630" Height="310" Center="{Binding Converter={StaticResource GeopointConverter}, Mode=OneWay}"&gt;
      &lt;Maps:MapControl.Children&gt;
          &lt;BingMaps:Pushpin&gt;
               &lt;BingMaps:MapLayer.Position&gt;
                   &lt;BingMaps:Location Latitude="{Binding Latitude, Mode=OneWay}" Longitude="{Binding Longitude, Mode=OneWay}" /&gt;
               &lt;/BingMaps:MapLayer.Position&gt;
          &lt;/BingMaps:Pushpin&gt;
      &lt;/Maps:MapControl.Children&gt;
  &lt;/Maps:MapControl&gt;
  </code></pre>
  
  <p>This does add the pin at the correct location, but if I pan the map, the pin doesn't pan with it. I'm probably just missing something silly, but why doesn't the pin pan with the map?</p>
