Entity Framework 6 .FindAsync() with .Include()

I'm new to the Async() world of EF and I was wondering if this was possible. My Google searches rendered no answers.

I have two classes:

public class User {
    [Key]
    public int Id { get; set; }
    public string Name { get; set; }
}

public class Application {
    [Key]
    public int Id { get; set; }
    public string Description { get; set; }

    [ForeignKey("User")]
    public int UserId { get; set; }
    public User User { get; set; }
}

My Details route for Application is as follows:

public async Task<ActionResult> Details(int? id) {
    if (id == null) {
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }
    Application application = await db.Applications.FindAsync(id);
    if (application == null) {
        return HttpNotFound();
    }
    return View(application);
}

The code above for details returns null for application.User.Name

I've seen calls to get the foreign object data like db.Applications.Include(a => a.User). How can I combine both of these? Or maybe something other than .include() is to used here.

Thanks.
