如果您使用基于WinRT的Store App模板进行项目，则可以不能访问一些旧的Silverlight API。我现在不确定是否包括Microsoft.Phone，但我相信如此。您将不得不研究执行相同任务的新API。

If you are doing a project using the WinRT based Store App template you can't access some of the old Silverlight APIs. I'm right now not sure wether that includes Microsoft.Phone but I believe so. You will have to look into new APIs doing the same task.

您具体要寻找什么功能？

What functionality are you looking for specifically?
