Convert lines of C# code from asp.net mvc 5 under visual studio 2015 to asp.net core2 under visual studio 2017

Hello, how can I made this code with asp.net core 2 under Visual studio 2017.

 app.UseFacebookAuthentication(new FacebookAuthenticationOptions
            {
                
                AppId = "**************",
                AppSecret = "************",
                Scope = { "email", "manage_pages", "pages_show_list", "user_likes", "user_events", "user_videos", "user_photos", "user_status", "publish_pages" },
                Fields = { "birthday", //User's DOB  
                           "picture", //User Profile Image  
                           "name", //User Full Name  
                           "email", //User Email  
                           "gender", //user's Gender  
                        },

                Provider = new PopupFacebookProvider
                {
                    OnAuthenticated = context =>
                    {
                        context.Identity.AddClaim(new System.Security.Claims.Claim("FacebookAccessToken", context.AccessToken));
                        return Task.FromResult(true);
                    }
                }
            });

the PopupFacebookProvider is a class. Thanks.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.Owin.Security.Facebook;

namespace ChartListOfObject.Models
{
    public class PopupFacebookProvider : FacebookAuthenticationProvider
    {
        public override void ApplyRedirect(FacebookApplyRedirectContext context)
        {
            context.Response.Redirect(context.RedirectUri + "&display=popup");
        }
    }
}

Want to convert just the first code Because I think the the second code is the same in vs2015 and vs 2017. 

thanks.
