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

Being new to theAsync() I pondered whether this was feasible in the world of EF. My Google searches came up empty.

I'm taking 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 path forApplication the following:

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 more information yieldsnull for application.User.Name

I've heard requests for the foreign object information, such asdb.Applications.Include(a => a.User) . How do I merge these two? or perhaps something different from.include() to be used in this.

Thanks.
