Well, I just changed the code complete:
 async void Button_Clicked(System.Object sender, System.EventArgs e)
 {
            var httpClient = new HttpClient();
            var resultJson = await httpClient.GetStringAsync("http://www.mi.traelopaq.net/listarpaqjson.php?text1=2264&text2=pOADSIQMASD.O398AJas&KEYAPI=ODUTRAS.9di23821@ldpli2skjs43&KEYPASo=OASmsjdu38IO1p29AA93JA0OD9K1221");

            var resultList = JsonConvert.DeserializeObject<Package[]>(resultJson);

            PaqueteList.ItemsSource = resultList;
        }
And Package is my json file:

 public class Package
    {
        
        [JsonProperty("peso")]
        public string Peso { get; set; }

        [JsonProperty("tracking_number")]
        public string TrackingNumber { get; set; }

        [JsonProperty("contenido")]
        public string Contenido { get; set; }
}


If you use postman and type the URL:
"http://www.mi.traelopaq.net/listarpaqjson.php?text1=2264&text2=pOADSIQMASD.O398AJas&KEYAPI=ODUTRAS.9di23821@ldpli2skjs43&KEYPASo=OASmsjdu38IO1p29AA93JA0OD9K1221"

You got an answer, but not in the programa, if it the same Error: Object Set without... and it is correct because there is not answer, But WHY? because it is works on postman.
