Does this extension allow debugging in cursor.sh for dotnet projects?

[dgokcin]

Hello

could you please describe/document how to get this debugger to work in cursor if it is still working with cursor? I tried bunch of different combinations but I am not able to get it to work. I would like to be able to debug a web api project and a console project either with dotnet 6 or 7 as close as possible to the debugging experience in vscode.

Here are the steps I followed:

• On a clean IDE with no c# related extensions installed. I downloaded the latest version of this extension, extracted it and placed it under ${workspaceFolder}/netcoredbg.

• Created a new project with dotnet new console. Added the following launch.json and tasks.json.

  .vscode/tasks.json

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

  .vscode/launch.json

  {
    "version": "0.2.0",
    "configurations": [
      {
        "name": ".NET Core Launch (console) with pipeline",
        "type": "coreclr",
        "request": "launch",
        "preLaunchTask": "build",
        "program": "${workspaceFolder}/bin/Debug/net6.0/test.dll",
        "args": [],
        "cwd": "${workspaceFolder}",
        "stopAtEntry": true,
        "console": "internalConsole",
        "internalConsoleOptions": "openOnSessionStart",
        "logging": {
          "diagnosticsLog": {
            "protocolMessages": true
          }
        }
        // tried with different versions of dotnet
        // tried with & without this pipe transport
        // tried building netcoredbg from source and using that
        // tried downloading the latest release of netcoredbg and using that
        // tried with the free c# extension and without it
        // "pipeTransport": {
        //     "pipeCwd": "${workspaceFolder}",
        //     "pipeProgram": "bash",
        //     "pipeArgs": ["-c"],
        //     // tried with different debuggers including this extension, samsung
        //     "debuggerPath": "${workspaceFolder}/netcoredbg/netcoredbg"
        //   },
      },
      {
        "name": ".NET Core Attach",
        "type": "coreclr",
        "request": "attach",
        "processId": "${command:pickProcess}"
      }
    ]
  }

• Hit Debug(console)

I tried different combinations with the pipe transport, dotnet version etc. but the result is the same, debugger opens and closes and nothing happens in between or debugger hangs without hitting any of my breakpoints.

Note that this configurations works on vscode or vscode insiders with the official c# extension.

Did you ever find a resolution to this? I'm running into the same issue.

[dgokcin]

@cmerther nope. I gave up after trying for a week. I felt like I was getting close but nothing I tried has worked.

I got this extension to work in Cursor[1] (thanks to an unrelated video[2] and its referenced PR comment[3]).

These file configurations will allow debugging including hitting breakpoints:

launch.json (edit <net-runtime-folder> and <program-name> in pipeArgs below):

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": ".NET Core Launch (console)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "cwd": "${workspaceFolder}",
            "console": "internalConsole",
            "stopAtEntry": false,
            "logging": {
                "diagnosticsLog": {
                    "protocolMessages": true
                }
            },
            "internalConsoleOptions": "openOnSessionStart",
            "pipeTransport": {
                "pipeCwd": "${workspaceFolder}",
                "pipeProgram": "dotnet",
                "pipeArgs": [
                    "${workspaceFolder}/bin/Debug/<net-runtime-folder>/<program-name>.dll"
                ],
                "quoteArgs": true
            }
        },
        {
            "name": ".NET Attach",
            "type": "coreclr",
            "request": "attach",
        }
    ]
}

tasks.json (edit <program-name> in args below):

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "command": "dotnet",
            "type": "shell",
            "args": [
                "build",
                "${workspaceFolder}/<program-name>.csproj",
                "/property:GenerateFullPaths=true",
                "/consoleloggerparameters:NoSummary"
            ],
            "group": "build",
            "presentation": {
                "reveal": "silent"
            },
            "problemMatcher": "$msCompile"
        }
    ]
}

Hope it helps.

were you able to hit the break point on a mac or on linux? @VoidMonk

[VoidMonk]

I tried on Windows and latest Cursor, and it hits breakpoints the first few times only, but this extension doesn't work reliably every time with Cursor. Not sure what/where the problem is.

As an alternative, I downloaded the netcoredbg[1] debugger that this extension uses, and tried it directly. That seems to work every time, by changing pipeTransport in launch.json as follows:

"pipeTransport": {
    "pipeCwd": "${workspaceFolder}",
    "pipeProgram": "cmd",
    "pipeArgs": [
        "/c",
    ],
    "debuggerPath": "<full-path-to-netcoredbg-executable",
    "debuggerArgs": [
        "--interpreter=vscode",
        "--",
    ],
    "quoteArgs": true
}

On a mac you can try replacing cmd with zsh (and remove the pipe arg). In Linux you can try replacing cmd with bash or similar shell (and replace the pipe arg accordingly).

So, I'm not sure what benefits this extension provides over just using netcoredbg directly. Maybe @muhammadsammy can clarify or help resolve this issue.
