If you’re developing applications for Windows phone, you’ve probably read about the Standard and Advanced Anti-Piracy Protection available to developers to help protect your hard developed IP. Advanced Anti-Piracy Protection (AAPP) is designed to thwart the illegitimate sharing of your Windows phone applications. Even if a hacker obtains the binaries from one device, AAPP will prevent that application from running on any other device.
