I am using TweetSharp to send tweets to users (currently testing it) however it keeps coming back with Bad Authentication Data 

`{"errors":[{"code":215,"message":"Bad Authentication data."}]}`

I have checked my app settings and it has full read and write access. I have also tried to regenerate my consumer keys but still not luck.

here is my code

```
public ActionResult AccessToken()
{

     string oauth_consumer_key = "<consumer key>";
     string oauth_consumer_secret = "<consumer secret>";

     var service = new TwitterService(oauth_consumer_key, oauth_consumer_secret);

     // Now we need the Token and TokenSecret
     OAuthRequestToken requestToken = service.GetRequestToken("http://localhost:37808/");
     string authURL = service.GetAuthorizationUri(requestToken).ToString();

     Process.Start(authURL);

     SendTweetOptions options = new SendTweetOptions();
     options.Status = "Hello there Twitter";

     service.SendTweet(options);

     var re = service.Response.Response;

     return View();            
    }

```

Am I doing anything wrong?
