Pex for fun

Windows Phone

Download Pex4Fun for WP7



    Windows Phone 7 exclusive, sadly
    In-built courseware allows users to get up to speed with all three languages, even if they have no prior programming experience - and while the app won't make you into a world-class coder overnight, it's a neat way to get involved in programming - and a nice way for Microsoft to boost its prospective Windows Phone developer pool.
