I am new to Xamarin.forms and need to use maps for UWP platform. I have installed Xamarin.Forms.Maps nuget package in my PCL. And have called the init function in the App.xaml.cs of UWP section as follows:

Xamarin.Forms.Forms.Init(e); Xamarin.FormsMaps.Init("TokenKey");
----------------------------------------------------------------

However, the maps is not visible on deploying. I have added some pins as well and what I see is some blue screen, with the pins. I have tried lot of options, but have found no luck yet.
 Below is the code snippet for calling maps:

```
Map map = new Map(MapSpan.FromCenterAndRadius(new Position(51.5074, 0.1278), Distance.FromMiles(10)));
        map.MapType = Xamarin.Forms.Maps.MapType.Hybrid;
        map.HeightRequest = 700;
        map.WidthRequest = 725;
        map.IsShowingUser = true;
        var position1 = new Position(51.5033, 0.1195);
        var pin1 = new Pin { Type = PinType.Place, Position = position1, Label = "label1", Address = "address1" };
        map.Pins.Add(pin1);
        var position2 = new Position(51.5014, 0.1419);
        var pin2 = new Pin { Type = PinType.Place, Position = position2, Label = "label1", Address = "address1" };
        map.Pins.Add(pin2);
        this.mapGrid.Children.Add(map);

```

Am I doing anything wrong ? Or is there any missing reference that I should be adding to make this work ? Please help me out.
P.S- The same solution loads a map on my colleague's machine, but doesn't work on others' machines.
