Today, Microsoft published the latest version of the Windows Phone SDK 7.1. This Release Candidate delivers the finalized API’s as well as the ‘Go Live’ license which will allow developers to submit their apps to Windows Marketplace. All current Windows Phone publishers are being asked to use this latest SDK to update their current apps and resubmit them to take advantage of new Window Phone capabilities.
New Profilers and Marketplace Test kits are new additions in the Release Candidate version of the SDK to accelerate the time to complete technical certificate testing.
Further information and release notes can be found in the Windows Phone section of Nokia Developer.
