 public async Task SendHttpClientRequest( Uri uri )
            {
            try
                {
                HttpClient client = new HttpClient();
                HttpResponseMessage response = await client.GetAsync( uri );
                response.EnsureSuccessStatusCode();
                string responseBody = string.Empty;
                responseBody = await response.Content.ReadAsStringAsync();
                }
            catch ( HttpRequestException e )
                {
                Debug.WriteLine( "\nException Message :{0} ", e.Message );
                }
            }
