how to add google map in windows phone 8 app - google-maps

Question

I am developing an app which uses Map service for Windows Phone 8.
I followed a link
http://themightyhedgehog.blogspot.de/2013/01/how-to-use-google-maps-in-your-own.html
and tries to develop an app containing Google Map.
But I got an error in Xaml on line
MapAppScope:BindingHelpers.TileSource="{Binding GoogleMap}"
and the error I got are:
BuildingHelpers is not supported in Silverlight.
The attachable property 'TileSource' was not found in type 'BuildingHelpers'.
The Namespace prefix "MapAppScope" is not defined.
In Xaml:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<Microsoft_Phone_Controls_Maps:Map
Name="MyMap"
Grid.Column="1"
LogoVisibility="Collapsed"
d:LayoutOverrides="GridBox"
MapAppScope:BindingHelpers.TileSource="{Binding GoogleMap}"
Margin="0,0,0,2">
<Microsoft_Phone_Controls_Maps:Map.Mode>
<MSPCMCore:MercatorMode/>
</Microsoft_Phone_Controls_Maps:Map.Mode>
</Microsoft_Phone_Controls_Maps:Map>
</Grid>
In .CS:
namespace Google_Map_App
{
public enum GoogleType
{
Street = 'm',
Hybrid = 'y',
Satellite = 's',
Physical = 't',
PhysicalHybrid = 'p',
StreetOverlay = 'h',
WaterOverlay = 'r'
}
public class Google : TileSource
{
public Google()
{
MapType = GoogleType.Street;
UriFormat = #"http://mt{0}.google.com/vt/lyrs={1}&z={2}&x={3}&y={4}";
}
public GoogleType MapType { get; set; }
public override Uri GetUri(int x, int y, int zoomLevel)
{
return new Uri(
string.Format(UriFormat, (x % 2) + (2 * (y % 2)),
(char)MapType, zoomLevel, x, y));
}
}
public static class BindingHelpers
{
//Used for binding a single TileSource object to a Bing Maps control
#region TileSourceProperty
// Name, Property type, type of object that hosts the property, method to call when anything changes
public static readonly DependencyProperty TileSourceProperty =
DependencyProperty.RegisterAttached("TileSource", typeof(TileSource),
typeof(BindingHelpers), new PropertyMetadata(SetTileSourceCallback));
// Called when TileSource is retrieved
public static TileSource GetTileSource(DependencyObject obj)
{
return obj.GetValue(TileSourceProperty) as TileSource;
}
// Called when TileSource is set
public static void SetTileSource(DependencyObject obj, TileSource value)
{
obj.SetValue(TileSourceProperty, value);
}
//Called when TileSource is set
private static void SetTileSourceCallback(object sender, DependencyPropertyChangedEventArgs args)
{
var map = sender as Map;
var newSource = args.NewValue as TileSource;
if (newSource == null || map == null) return;
// Remove existing layer(s)
for (var i = map.Children.Count - 1; i >= 0; i--)
{
var tileLayer = map.Children[i] as MapTileLayer;
if (tileLayer != null)
{
map.Children.RemoveAt(i);
}
}
var newLayer = new MapTileLayer();
newLayer.TileSources.Add(newSource);
map.Children.Add(newLayer);
}
#endregion
}
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
// Sample code to localize the ApplicationBar
//BuildLocalizedApplicationBar();
}
}
}

Note that using Google Maps tiles in the Bing Maps WP8 or Windows 8 control is against the terms of use of both the Bing Maps and Google Maps API's. Any app found in the app store doing this will be removed.
