Pex for fun is a project from a research team which is part of the Research in Software Engineering (RiSE) group at Microsoft Research . Pex for fun allows programming in C#, Visual Basic, and F# from our browser. Now the team has released a mobile app which allows you to do the same in Windows Phone 7.
Win points by writing code! You earn points when your code computes the right outputs for all inputs. Pex4fun features a code editor with auto-completion, snippets and background compilation to make programming on the phone a reality. If you are new to programming in general, don’t worry: Pex4fun also features a set of courses to learn the basics and beyond right from your phone.
