Windows Phone 8.1 SDK leak – All you need to know

On Monday, February 10th, Microsoft sent out private invites to a select number of Windows Phone developers. The content was the beta release of the Windows Phone 8.1 software development kit (SDK), which is what developers use to make apps. SDKs don’t reveal all of the consumer features, but they reveal enough about the 8.1 operating system to warrant interest.

Less than 24-hours later, an anonymous developer on link aggregation site Reddit leaked screenshots and details about the beta SDK and new OS. Since then, more information has come out from other developers as the SDK ISO file itself has leaked.
