我按照默认步骤操作
- install .NET Core， (linux-package-manager-ubuntu-1604(
- 在 VSCode 中创建并打开(ASP.NET 核心空(项目，(
cd ~/projects && dotnet new web -o my-api && cd my-api && code .( - add vscode tasks.json and launch.json(C# Extension(， (ms-dotnettools.csharp(
- 添加断点(在 VSCode 中(，
- 并开始调试(在 VSCode 中按 F5(。
但这不会启动网络服务器，也不会在断点处停止...... 它确实构建了项目，因为我可以看到在bin/Debug/netcoreapp3.1/中生成的文件。
在项目root中运行dotnet run，构建(恢复(并运行Web服务器，我可以浏览到 https://localhost:5001 和 http://localhost:5000。但无法调试...
这是创建的 vscode 文件
launch.json

F5首先显示Terminal选项卡，然后切换到 VSCode 中的Debug Console

Debug Console
-------------------------------------------------------------------
You may only use the Microsoft .NET Core Debugger (vsdbg) with
Visual Studio Code, Visual Studio or Visual Studio for Mac software
to help you develop and test your applications.
-------------------------------------------------------------------
这似乎是VS Code本身安装的问题，我只是重新安装了VS Code，问题就消失了。
sudo snap remove code
sudo snap install code --classic
虽然这个解决方案不令人满意，但我有一个假设，为什么会发生这种情况。
我使用 CLI 而不是使用 GUI 安装了模块。我这么说是因为我在运行 Web 应用程序时看到了安装日志。我想调试器的安装可能在我运行应用程序时尚未完成。这可能会导致包损坏。但是，只是卸载扩展程序并不能解决问题，所以我不确定发生了什么。
code --install-extension ms-dotnettools.csharp
如果重新安装对您不起作用，请告诉我，并尝试更改您的launch.json，将openExternally替换为debugWithChrome。我在重新安装VS Code的同时更改了设置。
我遇到了同样的问题。
首先重新启动系统，看看它是否得到修复。 否则，请尝试MathieuAuclair的解决方案，然后重新启动系统。
这对我有用。
