New Sensor Capabilites

Sensors: Good to KnowNeed hardware to debug most scenarios

Camera, motion, compass, & gyro require hardwareFor accelerometer, you can use the emulator!

Motion sensor will try it’s bestWorks best with all three sensorsWill also work if only compass and accelerometer are present

Camera Output for video recorded is MP4Always check for device specific support for Flash modeUse Y or YUV format for processing samples – faster than ARGB

The New Market Place

MarketPlace: ImprovementsChallenges Fixed

Support Responsiveness. 98% of support inquiries are now responded to within 24 hours

Free app submission limits. Increased limit from 5 to 100 per year

Market-specific registration challenges. Fixed registration form and postal code validation logic

Registration problems due to Xbox profile. Fixed the linking of developer profile information between App hub and xbox.com

Blank or incomplete test results. Now providing complete certification failure report

Challenges Remaining

App certification consistency and test results feedback.

ID validation process is cumbersome. Revamping individual validation process

W-8 form requirement (for non-US developers). Working to simplify and automate

Submission process has errors. Working to eliminate bottlenecks and streamline process

Registration payment failures for some. Fixing remaining payment exception scenarios.

Distribute pre-certified Apps to a Set of Beta UsersCapabilities

Developer selects List of Testers (up to 100)Developer sends Email with Private Deeplink to the Testers Only Testers selected in App Hub can test the Application and provide Feedback for 90 daysBeta cannot be updated

BenefitsNo need to unlock Phones to test Apps

New Beta Distribution Service
