Hello everybody,
I have a little app (in c# with xamary), in debug mode RUNS PERFECT, as soon as i create a REALEASE MODE the APP FAILED and when you select one options from the device: the app stop and exit, but only in RELEASE MODE.
This is the code:

using (HttpWebResponse wResp = (HttpWebResponse)wReq.GetResponse())
            {
                using (Stream s = wResp.GetResponseStream())
                {
                    using (TextReader tr = new StreamReader(s))
                    {
                        json = tr.ReadToEnd();                        
                        TrackingList.ItemsSource = trackingR;
                        dynamic result = JsonConvert.DeserializeObject(json);
                        foreach (dynamic paq in result)
                        {
                            string valor = sTracking;
                            string busqueda = paq.tracking_number;
                            if (busqueda.Substring(0,4) == valor)
                            {
                                existe = "SI";
                                                              
                                string contenido = "Contenido  " + ": " + paq.contenido ;
                                string peso = "Peso (Lbs) " + ": " + paq.peso ;
                                string estatus = "Estatus     " + ": " + paq.desc_estatus_proceso ;
                                                                
                                trackingR.Add(new TrackingResult { OutputResult = contenido});
                                trackingR.Add(new TrackingResult { OutputResult = peso });
                                trackingR.Add(new TrackingResult { OutputResult = estatus });              
                               
                                //var jsonContenido = "{[{" + contenido + peso + estatus + "}]}";
                                //finalJson = JsonConvert.SerializeObject(jsonContenido);
                            }
                        }
