Example

We want to convert from System.Device.Location.GeoCoordinate to Windows.Devices.Geolocation.GeoPoint . However when applying this conversion we need to change the way the Latitude property is reference.

We want to convert from this code:

-- Windows Phone 8 Silverlight --

public double RetrieveLatitude(GeoCoordinate c)
{
   return c.Latitude;
}

To the following code:

public double RetrieveLatitude(Windows.Devices.Geolocation.Geopoint c)
{
    return c.Position.Latitude;
}

We change use the RedirectProperty mapping action to perform this change:

          </map:CodeMap.Action>
        </map:CodeMap>
         ...
        <map:CodeMap Kind="MemberAccess" MemberName="Latitude">

        </map:CodeMap>
        <map:CodeMap Kind="MemberAccess" MemberName="Longitude">
          <map:RedirectProperty NewPropertyOwner="Position" NewProperty="Longitude"/>
        </map:CodeMap>
