title: Windows Phone 8 maps
body: <p>I have next XAML:</p>
  
  <pre><code>&lt;maps:Map x:Name="MyMap"  HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Height="410" Width="436" CartographicMode="Hybrid"&gt;
              &lt;toolkit:MapExtensions.Children&gt;
                  &lt;toolkit:Pushpin Visibility="Collapsed" x:Name="pushpin" Content="My Position"/&gt;
              &lt;/toolkit:MapExtensions.Children&gt;
          &lt;/maps:Map&gt;
  </code></pre>
  
  <p>And here is my C# code:</p>
  
  <pre><code>string[] tmp = result.ToString().Split(' ');
          MyMap.Center = new GeoCoordinate(double.Parse(tmp[0]), double.Parse(tmp[1]));
          MapLayer layer0 = new MapLayer();
          Pushpin pushpin0 = new Pushpin();
          pushpin0.Visibility = Visibility.Visible;
          pushpin0.GeoCoordinate = new GeoCoordinate(double.Parse(tmp[0]), double.Parse(tmp[1]));
          MapOverlay overlay0 = new MapOverlay();
          overlay0.Content = pushpin0;
          overlay0.GeoCoordinate = new GeoCoordinate(double.Parse(tmp[0]), double.Parse(tmp[1]));
          layer0.Add(overlay0);
  </code></pre>
  
  <p>My pushpin doesn't show up on the map, what i'm missing here?</p>
