如何配置VSCode的launch.json与tasks.json调试多C#项目

你有两种可行的配置方式，根据自身使用习惯选择即可：

1. 为每个项目单独配置（直观易上手） #

这种方式适合项目数量不多的场景，直接复制现有配置并修改项目相关路径和名称即可，切换项目时直接在启动面板选择对应配置。

修改后的launch.json： #

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": ".NET Core Launch (Test01)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build Test01",
            "program": "${workspaceFolder}/Test01/bin/Debug/net7.0/Test01.dll",
            "args": [],
            "cwd": "${workspaceFolder}/Test01",
            "console": "internalConsole",
            "stopAtEntry": false
        },
        {
            "name": ".NET Core Launch (Test02)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build Test02",
            "program": "${workspaceFolder}/Test02/bin/Debug/net7.0/Test02.dll",
            "args": [],
            "cwd": "${workspaceFolder}/Test02",
            "console": "internalConsole",
            "stopAtEntry": false
        },
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach"
        }
    ]
}

修改后的tasks.json： #

{
    "version": "2.0.0",
    "tasks": [
        // Test01 相关任务
        {
            "label": "build Test01",
            "command": "dotnet",
            "type": "process",
            "args": [
                "build",
                "${workspaceFolder}/Test01/Test01.csproj",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        },
        {
            "label": "publish Test01",
            "command": "dotnet",
            "type": "process",
            "args": [
                "publish",
                "${workspaceFolder}/Test01/Test01.csproj",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        },
        {
            "label": "watch Test01",
            "command": "dotnet",
            "type": "process",
            "args": [
                "watch",
                "run",
                "--project",
                "${workspaceFolder}/Test01/Test01.csproj"
            ],
            "problemMatcher": "$msCompile"
        },
        // Test02 相关任务
        {
            "label": "build Test02",
            "command": "dotnet",
            "type": "process",
            "args": [
                "build",
                "${workspaceFolder}/Test02/Test02.csproj",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        },
        {
            "label": "publish Test02",
            "command": "dotnet",
            "type": "process",
            "args": [
                "publish",
                "${workspaceFolder}/Test02/Test02.csproj",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        },
        {
            "label": "watch Test02",
            "command": "dotnet",
            "type": "process",
            "args": [
                "watch",
                "run",
                "--project",
                "${workspaceFolder}/Test02/Test02.csproj"
            ],
            "problemMatcher": "$msCompile"
        }
    ]
}

2. 通用配置方案（更高效，适合多项目） #

无需为每个项目重复编写配置，利用VSCode的动态命令变量，每次运行时选择要操作的项目，新增项目也不用修改配置文件。

通用版launch.json： #

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": ".NET Core Launch (Selected Project)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build selected project",
            "program": "${command:dotnet.getProgram}",
            "args": [],
            "cwd": "${command:dotnet.getProjectDirectory}",
            "console": "internalConsole",
            "stopAtEntry": false
        },
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach"
        }
    ]
}

通用版tasks.json： #

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build selected project",
            "command": "dotnet",
            "type": "process",
            "args": [
                "build",
                "${command:dotnet.getProject}",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        },
        {
            "label": "publish selected project",
            "command": "dotnet",
            "type": "process",
            "args": [
                "publish",
                "${command:dotnet.getProject}",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "problemMatcher": "$msCompile"
        },
        {
            "label": "watch selected project",
            "command": "dotnet",
            "type": "process",
            "args": [
                "watch",
                "run",
                "--project",
                "${command:dotnet.getProject}"
            ],
            "problemMatcher": "$msCompile"
        }
    ]
}

使用该配置时，每次启动调试或执行任务，VSCode会弹出列表让你选择目标项目，无需手动修改路径。
