GDC: Mobile-friendly XNA version 4 announced

Microsoft has gone to GDC this week to stage a first look at XNA 4.0, the latest edition of the firm’s development toolset.

Version 4.0’s central new feature is support for Windows Phone 7 Series, adding to its Xbox 360 and PC platforms.

Crucially, those platforms will be integrated within one another, according to a blog post from XNA lead program manager Michael Klucher.

“Through the Gamer Services API’s you can pull in a user’s Gamertag and 2D Avatar as part of the game experience, unlock achievements on the platform, and leverage notifications for asynchronous turn based gaming,” he said.

Along with a cluster of graphical improvements, the XNA update also provides dynamic audio output as well as microphone input support.
