namespace Notes.Data
{
  public class Reply
  {
    public int Id { get; set; }
    public string Body { get; set; }
    public DateTime Created { get; set; }

    //The way to get back to the topic that owns it.
    public int TopicId { get; set; } // Entity will see the Id and the name of another type, and create a foreign key index
