I\'m writing a C# app that will be required to integrate with twitter, I need to be able to do the following:
I know that this post got marked as answered but I wanted to share how easy it is to send messages to multiple users at once with Tweetinvi (http://tweetinvi.codeplex.com/).
IToken token = new Token("userKey", "userSecret", "consumerKey", "consumerSecret");
ITokenUser u = new TokenUser(token);
// Publish Direct Message to all the followers
u.PublishMessage("Hello world!", u.followers);
// Done!
I believe this can be of great help to develop a twitter bot.
