Visual Studio 2019 for Mac：调试器未连接到 iOS 设备

Question

我正在尝试在全新的 MacBook Pro (Mojave) 上使用 visual studio 2019 调试一个长期受苦的 Xamarin 应用程序。

解决方案构建、传输到设备并启动应用程序，但调试器不会通过电缆或 wifi 连接。 Visual Studio 中用于 Mac 的虚拟项目也不会连接，但 xcode 中的虚拟项目会。

VS 只是说 "waiting for the debugger to connect to ... on port 10000 via Wifi"

这是我的 VS 详细信息：

Answer 1

首先确保xcode和visual studio版本是最新的。

也试试

通过点击图标手动启动应用程序
正在从设备中删除应用程序并重新部署它
正在重启设备
更改调试器端口

Answer 2

遗憾的是，这些错误现在通常隐藏在 VS 2019 中，Mac。您需要查看 Build Output window 以准确确定导致此故障的原因。

您描述的行为不属于特定类型的错误，它仅表示 VS 没有直观地显示其描述，而是因为运行进程在尝试放置构建时失败而卡住了在物理设备上。
