.Net Core-使用ANY dotnet命令可产生数千行输出，并需要几分钟的时间运行

标签： c# visual-studio .net-core visual-studio-2017

问题： 我遇到了dotnet命令的问题，这是我之前从未见过的：当我运行任何dotnet命令（甚至是dotnet --info时），该过程都需要花费几分钟的时间才能完成，并在其上产生数千行输出一台特定的机器。我已经在Visual Studio 2017、2019预览版和命令提示符中尝试了此操作，并获得了相同的结果。我也尝试过使用-v q或-v m标志手动设置详细程度，但这没有什么区别。

我相信，当我初次设置.net core时，我设置了某种类型的诊断或跟踪标志来导致这种现象，但是我不知道如何禁用它。我在运行核心的笔记本电脑上没有看到相同的问题。我现在使用笔记本电脑实际编译这些构建，因为在我的更强大的主开发计算机上，即使对于使用dotnet new创建的默认项目，每个构建都需要20分钟以上的时间。

例如，一个dotnet --info命令花费了4:50，并在这台机器上产生了6,937行输出。

我尝试过的事情：  -尝试使用Visual Studio 2017、2019预览版和命令提示符  -使用安静或最小详细程度标志  -重新安装Net Core

环境： Win7 x64 Net Core版本1.0-2.2.1

这完全是我启动dotnet --info命令时看到的输出。在其他机器上，此命令需要几秒钟才能运行，但是在这台机器上，则需要5分钟以上的时间，并且需要数千行的输出。首先，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显示方式。

解决方案： 我希望其他人以前已经见过此行为，并且可以指出正确的方向以关闭此跟踪/诊断类型输出。

您似乎已设置了跟踪环境变量。尝试从Powershell

运行 
$env:COREHOST_TRACE=0

，然后重新运行dotnet --info。
