C# code to publish, delete, retrieve tweets using oauth

The following C#.net class can be used to update statuses, delete, retweet statuses, obtain information regarding a particular status and any body who retweeted a particular status using status id.

This class implements all the methods that are under the “Tweets Resources” section in Twitter API documentation
