If you don't know about the TweetSharp library (google code) started off by Daniel Crenna and Jason Diller then, if you are interested in talking to the Twitter API from C# you should check it.

Yesterday I contributed a small MVC sample application to the project - I have been playing with a small "business" idea and it involves Twitter interaction. As a playpen I started off an MVC application, and then it started growing. It also happens that it has proved to be the playpen for a lot of the MVC/JSON/JQuery interations that my paying job is using right now, so it got even more legs due to that.

The sample application actually shows little about ASP.NET MVC, as almost all of the "heavy" work is done via JQuery Ajax calls, and the core View Engine stuff in MVC only provides the shell pages. It does however show quite a nice way (IMHO) of writing "Web 2.0" applications using ASP.NET MVC.

So if you are interested, go check it out ... all comments welcome, and I'm sure Daniel would appreciate anyone else who would like to commit to the project, either by making the sample applciation better, or by helping write, document and test the TweetSharp API itself.
