Object is always empty when deserialize on xamarin service - json

Question

Have this service built on a xamarin app:
public class OpenWeatherMap<T>
{
private const string OpenWeatherApi = "http://api.openweathermap.org/data/2.5/weather?q=";
private const string Key = "653b1f0bf8a08686ac505ef6f05b94c2";
HttpClient _httpClient = new HttpClient();
// aqui podemos enviar directo a una ciudad hardcoded
public async Task<T> GetAllWeathers(string city)
{
var json = await _httpClient.GetStringAsync(OpenWeatherApi + city + "&APPID=" + Key);
var getWeatherModels = JsonConvert.DeserializeObject<T>(json);
return getWeatherModels;
}
}
When i check the model object is always empty. JSON is fine and my class matches perfectly my JSON model. I'm using Newtonsoft.Json.
This is my model:
public class WeatherMainModel
{
[JsonProperty("coord")]
public Coord Coord { get; set; }
[JsonProperty("weather")]
public WeatherSubDetails[] Weather { get; set; }
[JsonProperty("base")]
public string Base { get; set; }
[JsonProperty("main")]
public Main Main { get; set; }
[JsonProperty("visibility")]
public string Visibility { get; set; }
[JsonProperty("wind")]
public WeatherWindDetails Wind { get; set; }
[JsonProperty("clouds")]
public Clouds Clouds { get; set; }
[JsonProperty("dt")]
public string Dt { get; set; }
[JsonProperty("sys")]
public WeatherSysDetails Sys { get; set; }
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("name")]
public string Name { get; set; }
[JsonProperty("cod")]
public string Cod { get; set; }
}
public partial class Clouds // new
{
[JsonProperty("all")]
public string All { get; set; }
}
public partial class Coord // new
{
[JsonProperty("lon")]
public string Lon { get; set; }
[JsonProperty("lat")]
public string Lat { get; set; }
}
public partial class Main
{
[JsonProperty("temp")]
public string Temp { get; set; }
[JsonProperty("pressure")]
public string Pressure { get; set; }
[JsonProperty("humidity")]
public string Humidity { get; set; }
[JsonProperty("temp_min")]
public string TempMin { get; set; }
[JsonProperty("temp_max")]
public string TempMax { get; set; }
}
public partial class WeatherSysDetails
{
[JsonProperty("type")]
public string Type { get; set; }
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("message")]
public string Message { get; set; }
[JsonProperty("country")]
public string Country { get; set; }
[JsonProperty("sunrise")]
public string Sunrise { get; set; }
[JsonProperty("sunset")]
public string Sunset { get; set; }
}
public partial class WeatherSubDetails
{
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("main")]
public string Main { get; set; }
[JsonProperty("description")]
public string Description { get; set; }
[JsonProperty("icon")]
public string Icon { get; set; }
}
public partial class WeatherWindDetails
{
[JsonProperty("speed")]
public string Speed { get; set; }
[JsonProperty("deg")]
public string Deg { get; set; }
}
I'm using visual studio community set for Latin America (Chile), so i tried changing every decimal field on the JSON to string on the model to avoid comma separation problems, but still, my object is coming empty no matter the JSON i inject to the deserializer.
Thanks in advance.
