-Location services currently available:
-            Usoniandream.WindowsPhone.LocationServices.Bing
-            Usoniandream.WindowsPhone.LocationServices.Nokia
-            Usoniandream.WindowsPhone.LocationServices.Stockholm
-
-The location services can be installed separately, but each of them rely on:
-            Usoniandream.WindowsPhone.LocationServices
-            Usoniandream.WindowsPhone.Extensions
-            Usoniandream.WindowsPhone.GeoConverter
-            RestSharp 102.7.0.0
-            Reactive Extensions 1.1

-
-To fetch all Stockholm City parking meters, one can use the following approach:
-
-            public ObservableCollection<LocationServices.Models.Stockholm.ParkingLocation> ParkingLocations { get; private set; }
-
-            var rxlocations = sthlmservicelayer.GetParkingLocationsByStreet(new Usoniandream.WindowsPhone.LocationServices.SearchCriterias.Stockholm.Parking.ParkingLocation.ParkingLocationsByStreet("Odengatan", Usoniandream.WindowsPhone.LocationServices.Models.Enums.Stockholm.VehicleTypeEnum.Car))
-                .ObserveOnDispatcher()
-                .Subscribe( x => { ParkingLocations.Add(x); });
-
-and, since it's observable/reactive, you're free to further extend it:
-
-            var rxlocations = sthlmservicelayer.GetParkingLocationsByStreet(new Usoniandream.WindowsPhone.LocationServices.SearchCriterias.Stockholm.Parking.ParkingLocation.ParkingLocationsByStreet("Odengatan", Usoniandream.WindowsPhone.LocationServices.Models.Enums.Stockholm.VehicleTypeEnum.Car))
-                .Take(20)
-                .ObserveOnDispatcher()
-                .Finally(() => IsDataLoading = false)
-                .Subscribe(
-                    // result
-                    x =>
-                    {
-                        ParkingLocations.Add(x);
-                    },
-                    // exception
-                    ex =>
-                    {
-                        MessageBox.Show(ex.Message);
-                    });
