title: Get current ApplicationUser in a PartialView
body: <p>New MVC 5 project has _LoginPartial that display current username:</p>
  
  <pre><code>@Html.ActionLink("Hello " + User.Identity.GetUserName() + "!", 
                   "Manage", 
                   "Account", 
                   routeValues: null, 
                   htmlAttributes: new { title = "Manage" })
  </code></pre>
  
  <p>I have added last/first name fields to ApplicationUser class, but can't find a way to display them instead of UserName. Is there a way to access ApplicationUser object? I have tried straightforward casting <code>(ApplicationUser)User</code> but it generates bad cast exception.</p>
