How to specify two navigation properties from entity X to the same target entity, Y?

Question

Consider that I have an Instructor class:

public class Instructor
{
    public InstructorTypesEnum Type { get; set; }

    public virtual ICollectio         


        

Answer 1

You can use the InversePropertyAttribute

On your model, I think it would be (not verified):

public class Instructor
{
  public InstructorTypesEnum Type { get; set; }

  [InverseProperty("Instructors")]
  public virtual ICollection Courses { get; set; }

  [InverseProperty("Coinstructors")]
  public virtual ICollection CoInstructingCourses { get; set; }
}
