Paul Yanez has published a tutorial in which he builds a Windows Phone 7 Twitter application.
First I would like to say that the code is from Scott Gu’s article Building a Windows Phone 7 Twitter Application using Silverlight. I am very excited that Silverlight will soon be capable of working on Windows Phones. Designing for the phone brings numerous design and user experience problems not associated with the average 20-30 inch computer monitors. About 6 months ago I began tackling those problems in my previous Blend tutorials for layout, animation and video within a iPhone interface.
