C# Entity Framework Basics Extending Our Entity Data Model Defining a Many-to-Many Relationship

I'm not sure what I am doing wrong

I have gone over this code many times and I keep getting this error

Course.cs(7,16): error CS1520: Class, struct, or interface method must have a return type Compilation failed: 1 error(s), 0 warnings

I have rewatched the video over and over, and I'm not sure what I missed.

Course.cs
using System.Collections.Generic;
namespace Treehouse.CodeChallenges
{
    public class Course
    {
        //  Compiler complains: error CS1520: Class, struct, or interface method must have a return type
        public Students()

        {
            Students = new List<Student>();
            }
        public int Id { get; set; }
        public int TeacherId { get; set; }
        public string Title { get; set; }
        public string Description { get; set; }
        public int Length { get; set; }
        public Teacher Teacher { get; set; }

        public ICollection<Student> Students { get; set; }
    }
}
Student.cs
namespace Treehouse.CodeChallenges
{
    public class Student
    {
        public int Id { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
    }
}

Constructors are required to have the same name as the class itself, but the constructor you have created for the Courses class is named "Students" instead.

The compiler then sees it as a method instead of a constructor and complains about the missing return type.

Thank you!
