How to access Facebook profile information using ASP.NET MVC 5

I am developing a basic website in ASP.NET MVC 5 (using visual studio 2013). The site will use Facebook to authenticate users and to retrieve initial profile data. For example, to enter the stack through a stream with the username facebook..access, a profile photo, etc. Plz any help me the corresponding sample

startup.auth.cs

 FacebookAuthenticationOptions fbao = new FacebookAuthenticationOptions();
        fbao.AppId = "****";
        fbao.AppSecret = "*****";
        fbao.Scope.Add("email");
        fbao.Scope.Add("user_birthday");
        fbao.Scope.Add("user_hometown");

        fbao.SignInAsAuthenticationType = Microsoft.Owin.Security.AppBuilderSecurityExtensions.GetDefaultSignInAsAuthenticationType(app);

        app.UseFacebookAuthentication(fbao);

Account Controller -> Externallogincallback

   // GET: /Account/ExternalLoginCallback
    [AllowAnonymous]
    public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
    {
        ClaimsIdentity fboa = await AuthenticationManager.GetExternalIdentityAsync(DefaultAuthenticationTypes.ExternalCookie);
        //var email = ext.Claims.First(x => x.Type.Contains("emailaddress")).Value;
        var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
        if (loginInfo == null)
        {
            return RedirectToAction("Login");
        }

        // Sign in the user with this external login provider if the user already has a login
        var result = await SignInManager.ExternalSignInAsync(loginInfo, isPersistent: false);



        switch (result)
        {
            case SignInStatus.Success:
                return RedirectToLocal(returnUrl);
            case SignInStatus.LockedOut:
                return View("Lockout");
            case SignInStatus.RequiresVerification:
                return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = false });
            case SignInStatus.Failure:
            default:
                // If the user does not have an account, then prompt the user to create an account
                ViewBag.ReturnUrl = returnUrl;
                ViewBag.LoginProvider = loginInfo.Login.LoginProvider;
                return View("ExternalLoginConfirmation", new ExternalLoginConfirmationViewModel { Email = loginInfo.Email });
        }
    }

Account Viewer Model

public class ExternalLoginConfirmationViewModel
{
    [Required]
    [Display(Name = "Email")]
    public string Email { get; set; }
    public string UserName { get; set; }
}
