Did you forget to return the 'weatherForecast' in the method?

I'm getting the error mentioned in the title. Nothing else is mentioned under "editor". I've been looking at the code for a long time and I simply cannot see what I'm doing wrong.

Help with explanation will be appreciated!

Program.cs 
using System;
using System.IO;

namespace Treehouse.CodeChallenges
{
    public class Program
    {
        public static void Main(string[] arg)
        {
            public static ParseWeatherForecast<string[]> WeatherForecast(string values)
                {
                var weatherForecast = new WeatherForecast(string values)
                string[] values = WeatherStationId;
                 }
            return weatherForecast
        }

    }
}
WeatherForecast.cs 
using System;

/* Sample CSV Data

*/

namespace Treehouse.CodeChallenges
{
    public class WeatherForecast
    {
        public string WeatherStationId { get; set; }
    }
}

The message displayed is probably just the first issue detected, but there are a few:

  • the new method should not be inside the main method (they should both be in the class)
  • the return type should go before the method name
  • the syntax for generics (with <>'s) won't be needed here
  • the argument type should be "string[]" instead of "string"
  • the assignment and return statements both need semicolons at the end
  • the assignment should put one of the values into the new object
  • the "return" statement should go inside the the method code body
