Add the Newtonsoft.Json namespace to the 'WeatherForecast.cs' file.

I'm lost as to what I'm missing. If I click Preview, it doesn't show anything. I am still getting "Did you add the using directive for Newtonsoft.Json in the WeatherForecast.cs file?" What am I missing?

Program.cs 
using System;
using System.IO;
using System.Collections.Generic;

namespace Treehouse.CodeChallenges
{
    public class Program
    {
        public static void Main(string[] arg)
        {
        }

       public static WeatherForecast ParseWeatherForecast(string[] values)
       {
            var weatherForecast = new WeatherForecast();
            weatherForecast.WeatherStationId = values[0];
            DateTime timeOfDay;
            if (DateTime.TryParse(values[1], out timeOfDay))
            {
                weatherForecast.TimeOfDay = timeOfDay;
            }
            Condition condition;
            if (Enum.TryParse(values[2], out condition))
            {
                weatherForecast.Condition = condition;
            }
            int temperature;
            if (int.TryParse(values[3], out temperature))
            {
                weatherForecast.Temperature = temperature;
            }
            double precipitation;
            if (double.TryParse(values[4], out precipitation))
            {
                weatherForecast.PrecipitationChance = precipitation;
            }
            if (double.TryParse(values[5], out precipitation))
            {
                weatherForecast.PrecipitationAmount = precipitation;
            }
            return weatherForecast;
        }

        public static List<WeatherForecast> DeserializeWeather(string fileName)
        {
            var weatherForecasts = new List<WeatherForecast>();

            using (var reader = new StreamReader(fileName))
            using (var jsonReader = new JsonTextReader(reader))
            {
                var serializer = new JsonSerializer();
                weatherForecasts = serializer.Deserialize<List<WeatherForecast>>(jsonReader);
            }

            return weatherForecasts;
        }
    }
}
WeatherForecast.cs 
using Newtonsoft.Json.Treehouse.CodeChallenges;
using System;

namespace Newtonsoft.Json.Treehouse.CodeChallenges
{
    public class WeatherForecast
    {
        [JsonProperty(PropertyName = "weather_station_id")]
        public string WeatherStationId { get; set; }
        public DateTime TimeOfDay { get; set; }
        public Condition Condition { get; set; }
        public int Temperature { get; set; }
        public double PrecipitationChance { get; set; }
        public double PrecipitationAmount { get; set; }
    }

    public enum Condition
    {
        Rain,
        Cloudy,
        PartlyCloudy,
        PartlySunny,
        Sunny,
        Clear
    }
}

:point_right: It looks like you removed part of the provided code.

The challenge started with "using Newtonsoft.Json;" as one of the lines at the top of Program.cs, but it looks like you removed it (you should put it back).

The instructions tell you to put a similar line in the WeatherForecast.cs file, but instead you seem to have created something combining that namespace with the one of the file. You should also restore the file's namespace to what it was so that it will match the one in Program.cs.
