将 Xamarin.iOS 项目设置为临时生成 .ipa 文件时，转移到 VS2022 后出现 MT2002 错误。我没有使用 System.Diagnostics.PerformanceCounter 也没有引用它。链接仅设置为 SDK。有谁知道怎么解决吗？

根据 Hans Passant 的评论，作为答案：
将 Xamarin.iOS 项目设置为临时生成 .ipa 文件时，转移到 VS2022 后出现 MT2002 错误。我没有使用 System.Diagnostics.PerformanceCounter 也没有引用它。链接仅设置为 SDK。有谁知道怎么解决吗？
您可以参考链接中的解决方案：Error MT2002: 无法解析“System.Diagnostics....
要修复此错误，您可以尝试以下操作：
确保机器上安装了汇编系统，版本=4.0.0.0。您可以通过在 PowerShell 中运行 Install-Package System 命令来执行此操作。 在项目中引用程序集System，Version=4.0.0.0。您可以通过将程序集添加到项目的引用中来完成此操作。 检查程序集 System, Version=4.0.0.0 的文档以查看是否定义了 System.Diagnostics.PerformanceCounter 类型。 萨拉尔路径
