为什么我的 Windows 应用商店 (Metro) 应用程序没有出现在共享窗格中？

Question

我已将我的应用设置为共享目标（和源），并且我可以成功地与其他应用共享我的应用的内容，但是当我在另一个应用（例如 Mail 或 IE）中时，我无法与我的应用程序，因为它没有作为可用的共享目标应用程序出现在共享窗格中。

我已阅读并遵循 MSDN 文档，检查了示例，并且还在 Package.AppXManifest 文件中设置了共享目标声明。

为什么，我该如何解决这个问题？

        }

        base.OnNavigatedTo(e);
    }

App.xaml.cs：

    protected override void OnShareTargetActivated(ShareTargetActivatedEventArgs args)
    {
        var rootFrame = new Frame();
        rootFrame.Navigate(typeof(MainPage), args.ShareOperation);
        Window.Current.Content = rootFrame;
        Window.Current.Activate();
    }
