Xamarin.iOS:在 Visual Studio 2019 更新后无法运行 [英] Xamarin.iOS: Cannot run after Visual Studio 2019 Update
问题描述
我遇到了一个奇怪的情况，
i'm facing a strange situation,
更新 Visual Studio 2019 后，我无法在 iOS 中运行该应用程序，当我尝试从连接到 Mac 的 Windows 计算机上运行时会发生这种情况.但是当我使用 Visual Studio for Mac 而不是 Windows 运行应用程序时，应用程序运行没有问题.
After Updating Visual Studio 2019, i'm not able to run the application in iOS, this happen when i try to run from a Windows Computer Linked to a Mac. But when i run the app using Visual Studio for Mac instead of windows, the app run without issues.
我查看了 Xcode 的 VS 配置和路径，结果是正确的 (/Applications/Xcode.app).Mac 上的路径存在并且可以访问.
I looked into VS configurations and paths for Xcode and are correct (/Applications/Xcode.app).The path on the Mac exists and are reachables.
我尝试了以下解决方案，但不起作用:打开模拟器 --> 点击顶部菜单 Simulator --> 点击 **Reset Content and Settings.... **同样在 Windows 和 Mac 中，架构都是 x86_64.
I tried the following solution, but it doesn't work: Open simulator -- > click on the top menu Simulator --> click on **Reset Content and Settings.... ** Also in both Windows and Mac the Architectures are x86_64.

推荐答案
我终于解决了.
Windows 上的 VS 和 CoreSimulator.Framework 之间存在通信错误.
There´s a communication error between VS on Windows and CoreSimulator.Framework.
我运行以下命令从终端重新安装 CoreSimulator.Framework:
i ran the following commands to re-install CoreSimulator.Framework from Terminal:
sudo rm -Rf /Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/*
/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -runFirstLaunch
然后 Xamarin.iOS 项目的配置正在更改调试端口(新的)，在执行模式上的 iOS 运行选项上配置设置为默认无后台获取.
Then the configurations for Xamarin.iOS project was changing the Debugging port (New one), Configure over the iOS Run Options on Execution Mode set as Default no Background Fetch.
我希望它可以帮助解决此问题的其他人.
I hope it helps to others with this issue.
