title: Load referenced data types from custom Identity UserManager
body: <p>I have a custom <code>IdentityUser</code> called <code>ApplicationUser</code>:</p>
  <pre class="lang-cs prettyprint-override"><code>public class ApplicationUser : IdentityUser
  {
      public ICollection&lt;Board&gt; Boards { get; set; }
  }
  </code></pre>
  <p>When loading a user with <code>_userManager.GetUserAsync(User)</code> in a handler method, it loads an ApplicationUser but without the <code>Boards</code> collection.
  When working directly with an <code>DbContext</code>, I would use <code>_context.User.Include(u =&gt; u.Boards)</code> but this isn't possible with the <code>UserManager</code>?</p>
  <p>How do I solve this issue?</p>
  <hr />
  <p>My <code>ApplicationDbContext</code> currently looks like this:</p>
  <pre class="lang-cs prettyprint-override"><code>public class ApplicationDbContext : IdentityDbContext&lt;ApplicationUser&gt;
  {
      public ApplicationDbContext(DbContextOptions&lt;ApplicationDbContext&gt; options)
          : base(options)
      {
      }
  }
  
  
  </code></pre>
