The Live SDK is designed to make it even easier to use SkyDrive and other compatible services throughout your Windows Store apps. In addition, on Windows 8 your apps can offer zero-click single sign-on to users who have a Microsoft account.
From SkyDrive document sharing to Outlook.com contacts and calendars, it's easy to let your users connect and engage. Enable single sign-on for users of Windows 8, Outlook.com, and other compatible services.
Important update from Microsoft
We recently announced that we’ll begin to encourage Messenger users to start using Skype. As a result, the Messenger developer program will end. Existing implementations that use Mobile Service Proxy (MSP) will continue to work until March 2014. Please visit our Forums page for more details.
