getting a message from workspaces that I don't understand.

workspaces asking me if the StreamReader is wraped into a Using statement and it is. Don't know whats 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 List<WeatherForecast> DeserializeWeather(string fileName)
        {
            var weatherForecast = new List<WeatherForecast>();
            using ( var reader = new StreamReader(fileName))
            {

            }
            return weatherForecast;

        }






        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;
        }

It looks like you found a challenge bug! :beetle:

Apparently the challenge doesn't like the space between the open parenthesis and the keyword "var". Remove that space and you'll pass.

You might want to report this bug to Support. It could get you a "special Exterminator badge".
