Integrating Applications with the Windows Phone OS

Abstract

When a third-party application runs on a Windows Phone, it runs in an execution environment that is highly restricted. The Windows Phone OS must be restrictive in order to protect unsuspecting users of mobile devices from potential malicious application behavior, which may include stealing personal data stored on the phone, dialing phone numbers without users& knowledge, or corrupting other applications& data stores. One of the major restrictions that Windows Phone OS places on mobile applications is limiting them to their own execution environment, or sandbox, and not allowing them access to other applications& space or internals of the operating system. Sandboxing and other Windows Phone security features are covered in great detail in the last chapter of this book, Chapter 19.
