share link facebook update status wall using c#(facebook SDK) - facebook

Question

I am searching three days but not find solution of my problems. I hope you will help me solve my problems.
I succeeded to post on wall. But there is a problem when I post ds wall nobody (even my friends too) can see my post and not post on update status. Only I can see the wall post. I checked my facebook settings and wall posts property is public.
string[] extendedPermissions = new[] { "publish_stream", "offline_access" };
var fbLoginDialog = new FacebookLoginDialog(appId, extendedPermissions);
fbLoginDialog.ShowDialog();
if (fbLoginDialog.FacebookOAuthResult != null) {
if (fbLoginDialog.FacebookOAuthResult.IsSuccess) {
var fb = new FacebookClient(fbLoginDialog.FacebookOAuthResult.AccessToken);
dynamic result = fb.Get("/me");
string firstName = result.first_name;
string lastName = result.last_name;
string id = result.id;
dynamic parameters = new ExpandoObject();
parameters.message = "Check out this funny article";
parameters.link = "http://www.example.com/article.html";
parameters.picture = "http://www.example.com/article-thumbnail.jpg";
parameters.name = "Article Title";
parameters.caption = "Caption for the link";
parameters.description = "Longer description of the link";
parameters.actions = new { name = "View on Zombo", link = "http://www.zombo.com", };
parameters.privacy = new { value = "ALL_FRIENDS", };
parameters.targeting = new { countries = "US", regions = "6,53", locales = "6", };
dynamic result1 = fb.Post("me/feed", parameters);

Answer 1

I would suggest trying the following:
change parameters.privacy = new { value = "CUSTOM"}; and see if that helps.
be sure the friends are qualified in the targeting list.
be sure your app is not in sandbox mode otherwise, only developers/testers of the app can see the postings from that app.
