[UWP]项目从8.1 app升级 - Common.NavigationHelper错误

问题描述

我将我的win8.1项目升级到win10，但在'公共页面上有一个未定义的错误.NavigationHelper'在下面的代码中。 这是8.1 app页面中的默认代码。

I upgraded my win8.1 project to win10 but have an undefined error on a page for 'Common.NavigationHelper' in the below code.  This was default code in 8.1 app page.

这是多余的还是有一种新的写法。 我使用OnNavigatedFrom子，所以我需要下面这个，不是吗？

Is this redundant or is there a new way of writing this.  I use the OnNavigatedFrom sub so I would need the below for this, wouldn't I?

谢谢，

Kieran

Thanks,

是的，你是对的。 UWP应用程序中缺少Common.NavigationHelper，我建议您在
上检查此官方UWP XAML导航菜单示例
GitHub 。之后，请查看 AppShell 页面，了解如何在Windows Universal应用中实施导航。

Yes, you are right. The Common.NavigationHelper is missing in the UWP app, I would recommend you to check this official UWP XAML Navigation Menu sample onGitHub. After that please check the AppShell page to see how to implement the navigation in Windows Universal apps.
