Feature request: integrate debugging with `dotnet watch`

See original GitHub issue

Issue Description

Hi, im currently trying to set-up vscode in such a way that I can use both the debugger and dotnet watch run. When running dotnet watch run it spawns a new process eg weather.exe which the debugger can attach to. When you trigger a recompile however, dotnet watch run terminates the process weather.exe causing the debugger to also exit. This means that we have to restart the debugger every time the app is recompiled, which defeats the purpose of using dotnet watch in the first place.

I would suggest a configurable timeout for the debugger to give time to reattach to the previous instance once it gets detached.

I’ve attached launch.json, tasks.json and the log of my terminal after reloads, I’ve also included a repository down below.

Launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": ".NET Core Attach",
      "type": "coreclr",
      "preLaunchTask": "watch",
      "request": "attach",
      "processName": "weather.exe"
    }
  ]
}

Tasks.json

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "watch",
      "command": "dotnet",
      "type": "process",
      "args": [
        "watch",
        "run",
        "${workspaceFolder}/weather.csproj",
        "/property:GenerateFullPaths=true",
        "/consoleloggerparameters:NoSummary"
      ],
      "problemMatcher": "$msCompile",
      "isBackground": true
    }
  ]
}

I’ve created a fairly crude extension which works for now. dotnet watch attach.

Would however still like to see this actually implemented 😃

@Skrypt @MarcoMedrano @loligans

The issues you have mentioned have since been solved for my plugin dotnet watch attach

I specifically tested Ubuntu 22.04 and development in WSL from windows (should be similar to the development container)

Another developer contributed support for the M1 Macs.

If you encounter any issues, please let me know by creating an issue in this repository
