Entity Framework Inheritance

[Bars Dan]

Hello to all I tried an enterprise structure like below:

https://ibb.co/dLACW7

And my models are like so:
public class Course : Entities    {            public int Credits { get; set; }        public virtual ICollection<Enrollment> Enrollments { get; set; }        }  public enum Grade    {        A, B, C, D, F    }    public class Enrollment : Entities    {            public int CourseID { get; set; }        public int StudentID { get; set; }        public Grade? Grade { get; set; }        [ForeignKey("CourseID")]        public virtual Course Course { get; set; }        [ForeignKey("StudentID")]        public virtual Student Student { get; set; }          } public class Student: Entities    {              public string LastName { get; set; }        public string FirstMidName { get; set; }        public DateTime EnrollmentDate { get; set; }        public virtual ICollection<Enrollment> Enrollments { get; set; }          }  public class Entities:IEntity    {        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]        [Key]        public int ID { get; set; }        [Required]        public string Title { get; set; }    } public interface IEntity    {          int ID { get; set; }        //string Title { get; set; }    }

And my context:
  public EFBlogContext()            : base("Blogst")        {        }        public DbSet<Student> Students { get; set; }        public DbSet<Enrollment> Enrollments { get; set; }        public DbSet<Course> Courses { get; set; }        protected override void OnModelCreating(DbModelBuilder modelBuilder)        {            modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();                              base.OnModelCreating(modelBuilder);        }

And here is my up method:
       public override void Up()        {            CreateTable(                "dbo.Course",                c => new                    {                        ID = c.Int(nullable: false, identity: true),                       [color=red] Title = c.String(),[/color]                        Credits = c.Int(nullable: false),                    })                .PrimaryKey(t => t.ID);                        CreateTable(                "dbo.Enrollment",                c => new                    {                        ID = c.Int(nullable: false, identity: true),                        CourseID = c.Int(nullable: false),                        StudentID = c.Int(nullable: false),                        Grade = c.Int(),                    })                .PrimaryKey(t => t.ID)                .ForeignKey("dbo.Course", t => t.CourseID, cascadeDelete: true)                .ForeignKey("dbo.Student", t => t.StudentID, cascadeDelete: true)                .Index(t => t.CourseID)                .Index(t => t.StudentID);                        CreateTable(                "dbo.Student",                c => new                    {                        ID = c.Int(nullable: false, identity: true),                        LastName = c.String(),                        FirstMidName = c.String(),                        EnrollmentDate = c.DateTime(nullable: false),                    })                .PrimaryKey(t => t.ID);                    }

The Title property is generated only for Course entity and ID property for every entity??? Can you please help me why? Thanks in advance

Inheritance makes it possible to create complex models that better reflect how developers think and also reduce the work required to interact with those models. Inheritance used with entities serves the same purpose as inheritance used with classes.
