Can Entity Framework handle many to many relationship without an intersection object?

Question

Using database first model: Let\'s say we have the classic tables Student, Course and StudentCourse (the latter obviously having FKs t

Answer 1

You can do it in EF Code First using ICollections. For example:

public class Student 
{ 
    public int ID { get; set; }
    public string Name { get; set; }
    public virtual ICollection Courses { get; set; }

    public Student()
    {
        Courses = New HashSet();
    }
}

Repeat for Course and swap it all over. This will create three tables in your database (Student, Course and StudentCourse) with a m-to-m relationship. Most importantly StudentCourse will be an invisible linking table that has no Entity in your model.
