如何在linux(ubuntu)中使用vscode调试asp.net core 3.1

Question

我按照默认步骤操作

• 安装.NET Core，( linux-package-manager-ubuntu-1604 )
• 在 VSCode 中创建并打开（ASP.NET core 空）项目，( cd ~/projects && dotnet new web -o my-api && cd my-api && code .)
• 添加 vscodetasks.json 和 launch.json（C# 扩展），（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 bin/Debug/netcoreapp3.1/ 中生成的文件

在项目根目录中运行dotnet run，构建（恢复）并运行网络服务器，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
{
    // Use IntelliSense to find out which attributes exist for C# debugging
    // Use hover for the description of the existing attributes
    // For further information visit https://github.com/OmniSharp/omnisharp-vscode/blob/master/debugger-launchjson.md

    "configurations": [
        {
            "name": ".NET Core Launch (web)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            // If you have changed target frameworks, make sure to update the program path.
            "program": "${workspaceFolder}/bin/Debug/netcoreapp3.1/my-api.dll",
            "args": [],
            "cwd": "${workspaceFolder}",
            "stopAtEntry": false,
            // Enable launching a web browser when ASP.NET Core starts. For more information: https://aka.ms/VSCode-CS-LaunchJson-WebBrowser
            "serverReadyAction": {
                "action": "openExternally",
                "pattern": "^\\s*Now listening on:\\s+(https?://\\S+)"
            },
            "env": {
                "ASPNETCORE_ENVIRONMENT": "Development"
            },
            "sourceFileMap": {
                "/Views": "${workspaceFolder}/Views"
            }
        },
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach",
            "processId": "${command:pickProcess}"
        }
    ]
}

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

F5先显示Terminal-tab，然后切换到Debug ConsoleVSCode中的-tab

Terminal-tab

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

尽管这个解决方案并不令人满意，但我对为什么会发生这种情况有一个假设。

我使用 CLI 而不是使用 GUI 安装模块。我这么说是因为我在运行网络应用程序时看到了安装日志。我想当我运行应用程序时，调试器的安装可能尚未完成。这可能导致包损坏。但是，仅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，替换openExternally为debugWithChrome. 我在重新安装 VS Code 的同时更改了设置。
