重装.NET SDK后VS Code无法创建/加载Polyglot Notebook求助

IT部门卸载过.NET SDK 6，重装后VS Code出现以下异常：

1. 打开已验证可用的.dib格式笔记本时，窗口顶部进度条持续加载，无法打开；
2. 尝试创建新笔记本时无任何可见反应。

故障排查建议与解决方案 #

一、日志排查方向 #

• Dotnet Interactive扩展日志：在VS Code中按Ctrl+Shift+U打开输出面板，选择「Dotnet Interactive」选项卡，查看创建/打开笔记本过程中的错误详情
• Jupyter扩展日志：输出面板切换至「Jupyter」选项卡，检查是否存在连接失败、依赖缺失类的报错
• VS Code前端日志：通过「帮助 > 切换开发人员工具 > 控制台」，查看页面层面的异常信息

二、配置修改与组件操作 #

• 指定.NET SDK版本：在项目根目录创建global.json文件，强制使用.NET 6 SDK，内容如下：

  {
    "sdk": {
      "version": "6.0.414"
    }
  }
  

• 修复.NET安装：打开命令提示符，执行dotnet repair命令，自动修复.NET SDK/运行时的损坏或缺失组件
• 清理扩展缓存：删除VS Code扩展缓存目录中ms-dotnettools.dotnet-interactive-vscode和ms-toolsai.jupyter相关文件夹（Windows路径：%USERPROFILE%\.vscode\extensions），重启VS Code后重新安装对应扩展
• 检查架构兼容性：确认VS Code的系统架构（帮助 > 关于）与已安装的.NET SDK（x64）一致，避免x86/x64混合导致的兼容性问题
