title: How to Load Related Objects in EF?
body: <p>I have 3 models in EF Code First:</p>
  
  <pre><code>public class Book
  {
   public int Id { get; set; }
   public ICollection&lt;Author&gt; Authors{ get; set; }
  }
  
  public class Author
   {
    public int Id { get; set; }
    [Required(ErrorMessage = "")]
    [ForeignKey("AuthorName")]
    public int AuthorId{ get; set; }
    public User AuthorName{ get; set; }
    public bool Signed {get; set;}
    }
  
  public class User
   {
   public int Id { get; set; }
   public string Name{ get; set; }
   }
  </code></pre>
  
  <p>I use this code for select all AuthorName of BookId .</p>
  
  <pre><code>db.Book.Find(BookId).Authors.Where(e =&gt; e.Signed == false);
  </code></pre>
  
  <p>But AuthorName is null for this.</p>
