在 vs 中不使用 sln 和 vcxproj 来调试单个 C++ 文件

1. 添加 debug 配置
   

会生成以文件 CppProperties.json:

{
  "configurations": [
    {
      "inheritEnvironments": [
        "msvc_x64"
      ],
      "name": "x64-Debug",
      "includePath": [
        "${env.INCLUDE}",
        "${workspaceRoot}\\**"
      ],
      "defines": [
        "WIN32",
        "_DEBUG",
        "UNICODE",
        "_UNICODE"
      ],
      "intelliSenseMode": "windows-msvc-x64"
    }
  ]
}

2. 定义构建任务的过程：
   

生成文件 tasks.vs.json:

{
  "version": "0.2.1",
  "tasks": [
    {
      "taskLabel": "任务-main",
      "appliesTo": "main.cpp",
      "type": "launch",
      "command": "cl",
      "args": [
        "/EHsc",
        "/utf-8",
        "/MTd",
        "/Zi", // 生成完整的调试信息
        "main.cpp"
      ]
    }
  ]
}

3. 创建调试任务：
   

生成文件 launch.vs.json:

{
  "version": "0.2.1",
  "defaults": {},
  "configurations": [
    {
      "type": "native",
      "name": "main.exe",
      "project": "main.exe",
      "projectTarget": ""
    }
  ]
}

4. 选择调试目标：
   

打断点：

5. 调试的完整过程：
