New Post: Get previous tweets

ok i got it, the problem was not on the code but on my tweeter account. i did as pheonix told and it works now.

thanks a lot for you help.

other think that i was missing was the execute operation with credentials. i was not throwing any exception it just returns a empty result. maybe someone new on this would have the same issue so i let it here these mention

 var credentials = TwitterCredentials.CreateCredentials(twitterToken, twitterTokenSecrett, twitterConsumer_Key, twitterConsumer_Secret);
  TwitterCredentials.ExecuteOperationWithCredentials(credentials, () =>
            {
                var c = Tweetinvi.Timeline.GetMentionsTimeline(4);
            });
