        public LocationResponse Post(LocationRequest request)
        {
            DbContext context = new DbContext();

            string bing = string.Format("http://dev.virtualearth.net/REST/v1/Locations/{0},{1}?o=json&key={2}", 
                request.Point.Latitude,
                request.Point.Longitude, 
                System.Web.Configuration.WebConfigurationManager.AppSettings["BingApiToken"].ToString());

            HttpWebRequest webRequest = (HttpWebRequest)HttpWebRequest.Create(bing);
            WebResponse webResponse = webRequest.GetResponse();
            string statusDescription = ((HttpWebResponse)webResponse).StatusDescription;
            Stream stream = webResponse.GetResponseStream();
            StreamReader reader = new StreamReader(stream);
            string json = reader.ReadToEnd();

            reader.Close();
            stream.Close();
            webResponse.Close();

            JObject jObject = JObject.Parse(json);

            string rawCountry = ((string)jObject.SelectToken("resourceSets[0].resources[0].address.countryRegion")).ToUpper().Replace(" ", string.Empty);
            Country country = (context.Countries.Where(c => c.CountryName.ToUpper() == rawCountry)).SingleOrDefault();
            string rawProvince = ((string)jObject.SelectToken("resourceSets[0].resources[0].address.adminDistrict")).ToUpper().Replace(" ", string.Empty).Replace("CITY", string.Empty);
            Province province = (context.Provinces.Where(p => p.ProvinceName.ToUpper().Replace(" ", string.Empty) == rawProvince)).SingleOrDefault();

            LocationResponse response = new LocationResponse();
            response.Point = request.Point;
            response.CountryCode = country.CountryCode;
            response.CountryName = country.CountryName;
            response.ProvinceCode = province.ProvinceCode;
            response.ProvinceName = province.ProvinceName;

            return response;
        }
