如何使用预览API CloseRequested？ [英] How to use preview API CloseRequested?

问题描述

我正在尝试将此预览API用于  关闭请求：

I'm trying to use this preview API for CloseRequested:

https://docs.microsoft.com/en-us/uwp/api/windows.ui.core .preview.systemnavigationmanagerpreview

https://docs.microsoft.com/en-us/uwp/api/windows.ui.core.preview.systemnavigationmanagerpreview

但Visual Studio找不到命名空间：

Windows.UI.Core.Preview

But Visual Studio cannot find the namespace:
Windows.UI.Core.Preview

如何我可以使用这个API吗？这也适用于生产吗？

How can I make use of this API? Also is this usable in production?

推荐答案

你好，

如果要测试此预览功能，可能需要最新的内部预览操作系统和内部预览SDK。例如，最新的SDK版本是17686  https://blogs.windows.com/buildingapps/2018/06/12/windows-10-sdk-preview-build-17686-available-now/
和你可能需要整个环境来支持此预览功能。 

You may need the lasest insider preview OS and insider preview SDK if you want to test this preview feature. For example, the lastest SDK version is 17686 https://blogs.windows.com/buildingapps/2018/06/12/windows-10-sdk-preview-build-17686-available-now/ and you may need the entire environment to support this preview feature. 

祝你好运，

Barry
