       {
        var service = new TwitterService(consumerKey, consumerSecret);
        Action<OAuthAccessToken, TwitterResponse> act = new Action<OAuthAccessToken, TwitterResponse>((a, b) => Result(a, b));
        try
        {

        catch (Exception) {
        }

    private void Result(OAuthAccessToken a, TwitterResponse b)
    {

    }

I've read the Api v2 documentation but it's diferent than my method because some methods are new and different than the documentation reports....

thanks very much for help...

stab- have twitter ok'd you for xAuth? Apparently, it's only permissible if your app/apiKeys have been whitelisted for it.

Read this: https://dev.twitter.com/docs/oauth/xauth

Your other apps for iPhone may have used regular OAuth and not xAuth. Like dethSwatch said, Apps have to be approved by Twitter in order to use xAuth.

Only caveat with xAuth is you do not get access tokens to direct messages.
