C# C# Streams and Data Processing Serialization Deserializing with Json.NET

Why is my code not working? using (var jsonReader = new JsonTextReader(reader))

using (var jsonReader = new JsonTextReader(reader))

Program.cs
using System;

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

            using (var  reader = new StreamReader(fileName)); 
              using (var jsonReader = new JsonTextReader(reader));



            return weatherForecasts;

        }



        public static WeatherForecast ParseWeatherForecast(string[] values)
        {
            var weatherForecast = new WeatherForecast();
            weatherForecast.WeatherStationId = values[0];

The "using" statements should not have semicolons after them. The final one should have a code block ("{}") following it.
