Access facebook friendlist from Asp.net C# using graph API

Question

The user friend list return no data only summary with total friend count. I am working on a web application which will fetch logged in user face book friend list and then use their birthday to post birthday message in their profile.

Is there a way I can invite the Facebook friend and then access the user friend list because it is a web application.

enter code here
private List<Person> GetPersonFriendList(string access_token,string id)
    {
        List<Person> friendList = new List<Person>();
        string url;
        #region JSON.Net Friends

        //Friends URL
        url = "https://graph.facebook.com/v3.2/" + id + "/taggable_friends?access_token=" + access_token;


        JObject myFriends = JObject.Parse(requestFBData(url));

        //string id = "";
        //string name = "";

        //Loop through the returned friends
       foreach (var i in myFriends["data"].Children())
       {
         Person friend = new Person();
         friend.id = i["id"].ToString().Replace("\"", "");
        friend.name = i["name"].ToString().Replace("\"", "");
       friendList.Add(friend);
        }

        return  friendList;

        #endregion


    }

private static string GetFacebookUserJSON(string access_token) { string url = string.Format(" https://graph.facebook.com/me?access_token= {0}&fields=email,name,first_name,last_name,link", access_token);

        WebClient wc = new WebClient();
        Stream data = wc.OpenRead(url);
        StreamReader reader = new StreamReader(data);
        string s = reader.ReadToEnd();
        data.Close();
        reader.Close();

        return s;
    }

taggable_friends is deprecated: https://developers.facebook.com/docs/graph-api/reference/user/taggable_friends/

This edge was deprecated on April 4th, 2018 and now returns an empty data set.

There is no way to access the whole friendlist anymore, you can only get a list of users who authorized your App too, with /me/friends .

...use their birthday to post birthday message in their profile

A friend would need to authorize your App with the user_birthday permission for that. Rule of thumb: No data at all from any user without his explicit authorization/permission.

Also, posting on the wall of another user is not possible since a very long time and would be spam - you are not allowed to autopost or prefill anyway. Last but not least, you cannot even post to your own wall anymore, because publish_actions was deprecated too.
