What am I missing as my return type on the Teacher.cs class?

The compiler says I'm missing a return type for my contructor, but I have it mirroring all the correct data as shown from the instruction video. Please advise on this problem!

Course.cs 
namespace Treehouse.CodeChallenges
{
    public class Course
    {
        public int Id { get; set; }
        public string Title { get; set; }
        public string Description { get; set; }
        public int Length { get; set; }

        public int TeacherId {get; set;}
        public Teacher Teacher {get; set;}
    }
}
Teacher.cs 
using System.Collections.Generic;

namespace Treehouse.CodeChallenges
{
    public class Teacher
    {
        public Courses()
        {
            Courses = new List<Course>();
        }

        public int Id { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }

        public ICollection<Course> Courses {get; set;}
    }
}

method name should be

public Teacher() { Courses = new List<Course>(); }
