Windows Phone 7.1-7.8应用程序与Windows Phone 8设备之间的兼容性
Windows Phone 7.1-7.8应用程序在Windows Phone 8设备上是否运行得很好? 在兼容性方面，我是否有理由选择一个而不是另一个?
Do Windows Phone 7.1 - 7.8 apps run reasonably well on Windows Phone 8 devices? Is there any reason in terms of compatibility for me to choose one over the other?
您将在以下链接中找到有关WP 7.1和WP 8平台兼容性的官方文档:
You will find the official documentation about WP 7.1 and WP 8 platform compatibility in the following link:
尽管通常任何WP7应用程序都可以在WP 8设备中正常运行，但本文档解决了某些行为可能不同的情况.
Although in general any WP7 app will run without problem in a WP 8 device, this documentation addresses some cases where the behavior may be different.
因此，如果您不使用WP 8中引入的任何特定功能，则可以开发目标WP 7.1.这样，您的应用将可供更多人使用.如果您想利用WP 8的特定功能(例如NFC或诺基亚地图)，我建议为这两种平台进行开发，并尽可能多地重用代码.
So, if you don't use any specific features introduced in WP 8, you can develop targetting WP 7.1. That way your app will be available for more people. If you want to take advantage of WP 8 specific features such as NFC or Nokia maps, I would recommend to develop for both platforms, reusing as much code as you can.
