Send device's current location to Azure service in Windows 8.1 - azure

Question

I am developing a location tracking windows mobile app and I want to send my current location to azure service as a background task. Getting current location is done. Currently I show the current location in the app tile. Likewise showing location in the tile I want to send location to the azure service. But how can I send my current location to azure service continuously so rest of the devices can see the device's location.
So far my code
public sealed class BackgroundGeofenceTask : IBackgroundTask
{
//Azure Service
//private MobileServiceCollection<Location, Location> items;
//private IMobileServiceTable<Location> LocationTable = App.WayToSchool5Client.GetTable<Location>();
BackgroundTaskDeferral _deferral = null;
Accelerometer _accelerometer = null;
Geolocator _locator = new Geolocator();
public void Run(IBackgroundTaskInstance taskInstance)
{
_deferral = taskInstance.GetDeferral();
try
{
// force gps quality readings
_locator.DesiredAccuracy = PositionAccuracy.High;
taskInstance.Canceled += taskInstance_Canceled;
_accelerometer = Windows.Devices.Sensors.Accelerometer.GetDefault();
_accelerometer.ReportInterval = _accelerometer.MinimumReportInterval > 5000 ? _accelerometer.MinimumReportInterval : 5000;
_accelerometer.ReadingChanged += accelerometer_ReadingChanged;
}
catch (Exception ex)
{
// Add your chosen analytics here
System.Diagnostics.Debug.WriteLine(ex);
}
}
void taskInstance_Canceled(IBackgroundTaskInstance sender, BackgroundTaskCancellationReason reason)
{
_deferral.Complete();
}
async void accelerometer_ReadingChanged(Windows.Devices.Sensors.Accelerometer sender, Windows.Devices.Sensors.AccelerometerReadingChangedEventArgs args)
{
try
{
if (_locator.LocationStatus != PositionStatus.Disabled)
{
try
{
Geoposition pos = await _locator.GetGeopositionAsync();
XmlDocument xml = TileUpdateManager.GetTemplateContent(TileTemplateType.TileSquare150x150Text03);
var tileElements = xml.GetElementsByTagName("text");
tileElements[0].AppendChild(xml.CreateTextNode(pos.Coordinate.Point.Position.Latitude.ToString("f5")));
tileElements[1].AppendChild(xml.CreateTextNode(pos.Coordinate.Point.Position.Longitude.ToString("f5")));
tileElements[2].AppendChild(xml.CreateTextNode(pos.Coordinate.Point.Position.Altitude.ToString("f0")));
TileNotification tile = new TileNotification(xml);
TileUpdater updater = TileUpdateManager.CreateTileUpdaterForApplication();
updater.Update(tile);
//Send locationto azure
//var db = new Location { ServiceId = "sID", CurrentLatitude = pos.Coordinate.Point.Position.Longitude.ToString(), CurrentLongitude = pos.Coordinate.Point.Position.Longitude.ToString() };
//await LocationTable.InsertAsync(db);
}
catch (Exception ex)
{
if (ex.HResult != unchecked((int)0x800705b4))
{
System.Diagnostics.Debug.WriteLine(ex);
}
}
}
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
}
public void Dispose()
{
if (_accelerometer != null)
{
_accelerometer.ReadingChanged -= accelerometer_ReadingChanged;
_accelerometer.ReportInterval = 0;
}
}
}
Location.cs
public class Location
{
public string ServiceId { get; set; }
public string CurrentLatitude { get; set; }
public string CurrentLongitude { get; set; }
}
