Empty Migrations are generated in code first ASP.NET MVC

I have been trying to generate migration but some reason, generated migrations is empty except the basic definition of function up and down but empty inside.

Model class

public class StoryDB
{
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public Guid id { get; set; }
    [Required]
    public string StoryContent { get; set; }
    private int heartsCount { get; set; }
    private int commentsCount { get; set; }
    private int shareCount { get; set; }
    public DateTime dateCreated { get; set; }
    public DateTime dateModified { get; set; }
}

Database Context class

public class StoreDB : DbContext { public StoreDB() : base("DefaultConnection") {

    }
    public virtual DbSet <StoryDB> Stories { get; set; }

}

Note that I am using the same connection DefaultConnection which is used to by Identity Classes When I generate the initial seeding class that generates perfectly (i.e. all user tables like roles and users) However when i try to generate the first migration after seed class, then nothing appears in the class

You have to tell the DbContext which entities you want to map to the DB. In your case StoryDB:

    public class StoreDB : DbContext
    {
       public StoreDB() : base("DefaultConnection")
        {

        }
        public virtual DbSet<StoryDB> Stories { get; set; }

    }

Note that DbSet has a generic parameter, which tells EF the actual type to use.
