Xamarin.Forms 预览器不存在 [英] Xamarin.Forms Previewer not exist

问题描述

我无法使用 VS Community 2019 更新 16.9.2 找到或启动 Xamarin.Forms Previewer.正如您在我构建项目后从附加的屏幕截图中看到的那样，即使上下文菜单中的 View Designer 也不起作用 Shift，但我无法切换到 XAML 预览模式+ F7.我也无法在 View 菜单下找到 Xamarin.Forms Previewer其他窗口

我已经向微软团队报告了这个问题，也许下个版本会恢复，请稍等.

解决方案

I couldn't find or start Xamarin.Forms Previewer using VS Community 2019 update 16.9.2.

As far as I know, there is no XAML Previewer in Visual Studio 2019 version 16.9.2. For now, it use the Hot Reload insead and provide a live visual tree to receive a real-time view of your running XAML code. It shows a tree view of the UI elements of your running Xamarin.Forms application.

When you debug you project, by default, it appears on the IDE's left. If you don't see it, use Debug > Windows > Live Visual Tree to show it.

I have reported this problem for Microsoft team, maybe it will be restored in the next version, please wait a minute.
