WP7: Access built in events

Question

我想知道如何在Windows Phone中创建带有内置事件（如来电或电子邮件接收）启动的应用程序。

Answer 1

There are some things that you can add your app to. Perhaps you create a Photo App or a Music App. You can register your app as that type and it will prompt the user to open a photo or song with your app.

Outside of that though you cannot access phone events. Functions such as this are locked off to developers by Microsoft to provide added security to users and also provide a consistent experience across the platform.
