在 Windows 到 Raspberry Pi 上使用 VS Code 进行远程调试

Question

我需要帮助来设置我的 vscode 以便在我的 RPi 4 (Raspberry Pi OS x64) 上部署和调试 dotnet 应用程序，因为我无法附加 vscode 调试器。

应用程序已正确构建并部署在我的 RPi 上，我可以使用命令 dotnet ~/MyFirstApp/MyFirstApp.dll 通过 ssh 运行它，但是当我尝试使用调试运行它时vscode 的函数 returns 出现以下错误：

Could not execute because the specified command or file was not found.
Possible reasons for this include:
  * You misspelled a built-in dotnet command.
  * You intended to execute a .NET program, but dotnet-~/MyFirstApp/MyFirstApp.dll does not exist.
  * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

这里是所有文件：

MyFirstApp.cs
```
Console.WriteLine("Hello, World!");
```

MyFirstApp.csproj

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
</Project>

可以应用两种不同类型的构建：Self-contained 和 Framework-dependent。

Self-contained 构建需要在 MyFirstApp 上运行 chmod +x（感谢@PMF 的建议）：

launch.json

{
       "name": ".NET Remote Launch - Self-contained",
       "type": "coreclr",
       "request": "launch",
       "preLaunchTask": "RaspberryPiDeploySelfContained",
       "program": "~/MyFirstApp/MyFirstApp",
       "args": [],
       "cwd": "~/MyFirstApp",
       "stopAtEntry": false,
       "console": "internalConsole",
       "pipeTransport": {
           "pipeCwd": "${workspaceRoot}",
           "pipeProgram": "ssh",
           "pipeArgs": [
               "pi@192.168.2.122"
           ],
           "debuggerPath": "~/vsdbg/vsdbg"
       }
}

tasks.json

{
       "label": "RaspberryPiPublishSelfContained",
       "command": "sh",
       "type": "shell",
       "dependsOn": "build",
       "windows": {
           "command": "cmd",
           "args": [
               "/c",
               "\"dotnet publish -r linux-arm64 -o bin\linux-arm64\publish\""
           ],
           "problemMatcher": []
       }

   },
   {
       "label": "RaspberryPiDeploySelfContained",
       "type": "shell",
       "dependsOn": "RaspberryPiPublishSelfContained",
       "presentation": {
           "reveal": "always",
           "panel": "new",
           "close": true
       },
       "windows": {
           "command": "scp -r bin\linux-arm64\publish\* pi@192.168.2.122:${workspaceFolderBasename}; ssh pi@192.168.2.122 chmod +x \"${workspaceFolderBasename}/${workspaceFolderBasename}\""
       },
       "problemMatcher": []
}

这个解决方案有效，但是，考虑到它是一个“self-contained”应用程序，它需要更多时间来复制所有依赖项并且需要更多磁盘 space。

Framework-dependent 解决方案需要复制更少的文件（更少的时间和磁盘 space 来部署和测试它）：

launch.json：我必须设置 args 字段提供路径 /home/pi/MyFirstApp/MyFirstApp.dll，我不明白为什么，但给出了路径~/MyFirstApp/MyFirstApp.dll 返回错误 Could not execute because the specified command or file was not found.

{
       "name": ".NET Remote Launch - Framework-dependent",
       "type": "coreclr",
       "request": "launch",
       "preLaunchTask": "RaspberryPiDeploy",
       "program": "~/.dotnet/dotnet",
       "args": ["/home/pi/MyFirstApp/MyFirstApp.dll"],
       "cwd": "~/MyFirstApp",
       "stopAtEntry": false,
       "console": "internalConsole",
       "pipeTransport": {
           "pipeCwd": "${workspaceRoot}",
           "pipeProgram": "ssh",
           "pipeArgs": [
               "pi@192.168.2.122"
           ],
           "debuggerPath": "~/vsdbg/vsdbg"
       }
}

           ],
           "problemMatcher": []
       }
   },
   {
       "label": "RaspberryPiDeploy",
