title: HttpPostedFileBase editor for using with EditorForModel
body: <p>Okay, maybe I'm missing something, but I can't figure this out. Using ASP.NET MVC 3, Razor views.</p>
  
  <p>I have a model object like this:</p>
  
  <pre><code>public class MyModel
  {
      public HttpPostedFileBase File { get; set; }
      public string Title { get;set; }
      public string Description { get; set; }
  }
  </code></pre>
  
  <p>When, in a strongly typed view, I call @Html.EditorForModel(), it only generates the Title and Description form fields.</p>
  
  <p>I created the file: Views\Shared\EditorTemplates\HttpPostedFileBase.cshtml, with dummy content, but it still doesn't get rendered.</p>
  
  <p>Is it possible to get EditorForModel to generate file input fields?</p>
