I have three models related Subject, UserSchools and Enroll_Teacher_Subjects. I want to make a query that get the information of UserSchools and the relations that Enroll_Teacher_Subjects have had with UserSchools. This works for me but I also need the information the object Subject that is inside the Enroll_Teacher_Subjects because I need NameSubject, DescriptionSubject. Always is null and I Cann´t place it in the include the query lambda.

public class Subject

{

    [Key]

    public int SubjectId { get; set; }

    [StringLength(50)]//only you can to write 50 characters

    [Display(Name = "Nombre de la Materia")]

    public string NameSubject { get; set; }





    [DataType(DataType.MultilineText)]

    [Display(Name = "Descripcion de la Materia")]

    public string DescriptionSubject { get; set; }



    [Display(Name = "Grado")]

    public int LevelId { get; set; }



    public virtual Level Level { get; set; }



    public virtual ICollection<Enroll_Teacher_Subject> Enroll_Teacher_Subjects { get; set; }

}

the model UserSchool

public class UserSchool

{



    [Key]

    public int UserId { get; set; }



    [Display(Name = "E-Mail")]

    [Required(ErrorMessage = "The field {0} is required")]

    [StringLength(50)]//only you can to write 50 characters

    [DataType(DataType.EmailAddress)]

    // [Index("UserNameIndex", Isnique = true)]

    public string EmailUser { get; set; }

            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);

        }



        var UserList = await db.UserSchools                                           

                                        .Include(x => x.Enroll_Teacher_Subjects)



                                        .Include(x => x.TypeDocument)

                                        .FirstOrDefaultAsync(x => x.UserId == id);



        if (UserList == null)

        {

            return HttpNotFound();

        }



        return View(UserList);

    }
