c# - 如何配置 Visual Studio Code 以从适用于 Linux 的 Windows 子系统 (WSL) 运行/调试 .NET (dotnet) Core？

Question

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:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": ".NET Core Launch (console)",
            "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

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 WSLinstalled, you might still have Ubuntu 14 in the WSL. If the versionis 14, run the following commands in a cmd prompt to reinstall andupdate 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。
