问题：我一直在dotnet命令中遇到了我以前从未见过的命令：当我运行任何dotnet命令，甚至dotnet --info时，该过程都需要几分钟才能完成，并在一台特定机器上产生数千条输出线。我已经在Visual Studio 2017、2019预览中尝试了此操作，并在命令提示符中获得了相同的结果。我还尝试使用-v Q或-V M标志手动设置冗长，但这没有区别。
我相信，当我第一次设置.NET核心时，沿线的某个地方，我设置了导致这种行为的某种类型的诊断或跟踪标志，但是我不知道如何禁用它。我在笔记本电脑上也看不到同样的问题，也正在运行核心。现在，我使用笔记本电脑实际编译了构建，因为每个构建都需要在我的主，更强大，开发机器上使用20分钟以上的时间，即使是使用dotnet new创建的默认项目。
举例来说，dotnet --info命令以4:50的速度命令，并在该计算机上产生了6,937行的输出。
我尝试过的东西： - 尝试Visual Studio 2017，2019预览和命令提示 - 使用安静或最小的冗长旗 - 重新安装Net Core
环境：Win7 X64Net Core版本1.0-2.2.1
这是逐字启动dotnet --info命令时我看到的输出。在其他机器上，此命令需要几秒钟才能运行，但是在这台计算机上，它需要超过5分钟的输出。为了提出一个想法，这只是前290行。开头附近的奇怪格式正是它在输出窗口中的出现方式。
分辨率：我希望其他人以前已经看过这种行为，可以将我指向正确的方向，以关闭此跟踪/诊断类型输出。
