##C#

var client = new HttpClient();
// Define the area from which the messages are to be retrieved
// Note: WBoundingBox.FromRadius is a helper method found in Skene Windows Phone project
var area = WBoundingBox.FromRadius(location, radiusMeters);
var locationStr = string.Format("&min_lat={0}&min_long={1}&max_lat={2}&max_long={3}",
  area.Min.Latitude.ToString(CultureInfo.InvariantCulture),
  area.Min.Longitude.ToString(CultureInfo.InvariantCulture),
  area.Max.Latitude.ToString(CultureInfo.InvariantCulture),
  area.Max.Longitude.ToString(CultureInfo.InvariantCulture));
// Convert date and time of the last successful get request to Unix time stamp
// so that we only get messages that game after that time
var lastGetTimeStamp = Utils.DateTimeToUnixTimestamp(lastGet);
// Create the parameters string
var getParameters = string.Format("?json=1&timestamp={0}", lastGetTimeStamp) + locationStr;
// Create the final URL
var uri = new Uri("http://whispr.outi.me/api/get_local_whispers" + getParameters);
// Send the request and get a result (JSON string)
var json = await client.GetStringAsync(uri);
// Deserialize the JSON string into a list of SkeneMessage objects
IEnumerable<Message> latestLocalMessages = JsonConvert.DeserializeObject<List<SkeneMessage>>(json);
