我在 Windows Subsystem for Linux 中安装了 .NET Core 2.2 (WSL) 并创建了一个新项目。我还为 Visual Studio Code 安装了 C# 扩展，语法突出显示和 IntelliSense 似乎可以正常工作。

但是，当我尝试使用调试器时，一切都停止了。这是我尝试对其进行配置的分步操作。

这是我的launch.json 文件:

            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceFolder}/bin/Debug/netcoreapp2.2/CodeCore.dll",
            "args": [],
            "cwd": "${workspaceFolder}",
            "console": "internalConsole",
            "stopAtEntry": false,
            "internalConsoleOptions": "openOnSessionStart"
        },
        {
            "name": ".NET Core Launch (web)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceFolder}/bin/Debug/netcoreapp2.2/CodeCore.dll",
            "args": [],
            "cwd": "${workspaceFolder}",
            "stopAtEntry": false,
            "internalConsoleOptions": "openOnSessionStart",
            "launchBrowser": {
                "enabled": true,
                "args": "${auto-detect-url}",
                "windows": {
                    "command": "cmd.exe",
                    "args": "/C start ${auto-detect-url}"
                },
                "osx": {
                    "command": "open"
                },
                "linux": {
                    "command": "xdg-open"
                }
            },
            "env": {
                "ASPNETCORE_ENVIRONMENT": "Development"
            },
            "sourceFileMap": {
                "/Views": "${workspaceFolder}/Views"
            }
        },
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach",
            "processId": "${command:pickProcess}"
        }
    ]
}

还有我的tasks.json 文件:

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "command": "dotnet build",
            "type": "shell",
            "group": "build",
            "presentation": {
                "reveal": "silent"
            },
            "problemMatcher": "$msCompile"
        }
    ]
}

我的目录结构:

但是当我点击“开始调试”按钮时，出现以下错误:

launch: program " does not exist

最佳答案

GitHub 上有一篇关于该主题的精彩文章 - Windows Subsystem for Linux .

长话短说，您需要先验证 Windows 10 之后的版本 Creators Update :

~$ cat /etc/os-release  | grep  -i version
VERSION="16.04.2 LTS (Xenial Xerus)"
VERSION_ID="16.04"
VERSION_CODENAME=xenial

注意以下事项:

If you had upgraded to Windows Creators update and already had WSL installed, you might still have Ubuntu 14 in the WSL. If the version is 14, run the following commands in a cmd prompt to reinstall and update WSL.

lxrun /uninstall /full
lxrun /install

下载调试器:

sudo apt-get install unzip
curl -sSL https://aka.ms/getvsdbgsh | bash /dev/stdin -v latest -l ~/vsdbg

调试器将安装在 ~/vsdbg/vsdbg。它是 debuggerPath。

用于启动的示例 launch.json 配置:

  {
           "name": ".NET Core WSL Launch",
           "type": "coreclr",
           "request": "launch",
           "preLaunchTask": "publish",
           "program": "/mnt/c/temp/dotnetapps/wslApp/bin/publish/wslApp.dll",
           "args": [],
           "cwd": "/mnt/c/temp/dotnetapps/wslApp",
           "stopAtEntry": false,
           "console": "internalConsole",
           "pipeTransport": {
               "pipeCwd": "${workspaceRoot}",
               "pipeProgram": "bash.exe",
               "pipeArgs": [ "-c" ],
               "debuggerPath": "~/vsdbg/vsdbg"
           }
       }

请注意:

• /.vscode/launch.json:这提供了一系列不同的配置，您可以使用这些配置来启动您的应用程序。调试 View 中有一个下拉菜单，用于选择激活的配置。
• /.vscode/tasks.json:这提供了一系列不同的任务，例如构建您的应用程序，您可以执行这些任务。调试配置可以通过 preLaunchTask 属性链接到这些任务之一。

示例“发布”任务 tasks.json (需要启动):

{
    "version": "2.0.0",
    "tasks": [
        ...,
        {
            "label": "publish",
            "command": "dotnet",
            "type": "process",
            "args": [
                "publish",
                "${workspaceFolder}/wslApp.csproj",
                "-o",
                "${workspaceFolder}/bin/publish"
            ]
        }
    ]
}

请注意:

• preLaunchTask 执行 dotnet publish，它在 Windows 上构建项目。由于 coreclr 是跨平台的，因此无需任何额外工作即可在 WSL 上执行二进制文件。

• pipeProgram 设置为 bash.exe。

• debuggerPath 指向 vsdbg，即 coreclr 调试器。

• 这将不支持想要从控制台读取的程序。

用于附加的示例 launch.json 配置:

 {
           "name": ".NET Core WSL Attach",
           "type": "coreclr",
           "request": "attach",
           "processId": "${command:pickRemoteProcess}",
           "pipeTransport": {
               "pipeCwd": "${workspaceRoot}",
               "pipeProgram": "bash.exe",
               "pipeArgs": [ "-c" ],
               "debuggerPath": "~/vsdbg/vsdbg",
               "quoteArgs": true
           }
       }

请注意:

• "processId": "${command:pickRemoteProcess}" 列出使用管道程序在 WSL 上运行的进程。
• quoteArgs 如果设置为 true，将用空格引用任何参数和调试器命令。
• 使用 sourceFileMap 来映射资源，如果它们在 与 build 地点不同的地点。如果你建立你的 在 Linux 中的项目，确保从 /mnt 驱动器添加 map 字母。示例:"sourceFileMap": { "/mnt/c/": "c:\\"}
• 文件和路径在 Linux 中区分大小写。
