Integrating Applications with the Windows Phone OS
When a third-party application such as yours runs on a Windows Phone, it executes in an environment that is highly restricted. 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 the user’s knowledge, or corrupting the data stores of other applications. 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 the internals of the operating system. Sandboxing and other Windows Phone security features are covered in greater detail in Chapter 19.
