问题:

I have the xamarin.forms application for which i am trying to connect localhost from PC to Iphone simulator in mac,Iam using the Ip address for connecting,

private string Uri = "http://192.168.0.16:62271/";//Windows Ip address:localhost port number     private string GetDishesUrl = "api/DishDetails/GetDishDetails?id=5";   try{      var httpClient = new HttpClient();     httpClient.BaseAddress = new Uri(Uri);      var response = await httpClient.GetAsync(new Uri(Uri + GetDishesUrl));     var stringAsync = await response.Content.ReadAsStringAsync();      if (response.IsSuccessStatusCode)     {         var responseJson = stringAsync;         return JsonConvert.DeserializeObject<List<DishDetails>>(responseJson);     } } catch(Exception ex) { } 

Here iam getting following Exception:
