"<div class='twitterUsuario'>Usuario " + Tweet.ScreenName + "</div>" + 
"<div class='twitterContenido'>" + Tweet.Text + "</div>" +

}   
this.mvTwitterAndrea.SetActiveView(this.vwTweets);            
}catch(Exception ex){    }     
}
}
}

********** And I have another class

Class ConfiguracionTwitter{
public ConfiguracionTwitter(){} 
public IEnumerable<Status> getHomeTimeLine(WebAuthorizer auth,int intCantidadTweets) {               
twitterContexto= new TwitterContext(auth);           
var tweets =        
(from tweet in twitterContexto.Status                       
where tweet.Type == StatusType.Home                        
select tweet).Take(intCantidadTweets).ToList();           
return tweets;        
}
}

Answer 1

A "401 Unauthorized" means that your application is unable to authenticate with Twitter. There are many things that can cause a 401. I've compiled a FAQ that will give you a list of things to check:

BTW, posting your OAuth keys makes your application insecure. You should visit your app on the Twitter page as soon as possible and generate a new set of keys.
