Research direction

Start by reproducing the WSL Ubuntu 22.04 setup using src/MIDebugEngine-Unix.sln, PublishOpenDebugAD7.sh, and the OpenDebugAD7.exe commands in the report. Compare the --server and --pauseForDebugger cases with the shown coreclr attach configuration, and inspect the reported missing coreclr.ad7Engine.json. Done means identifying why the connection or file lookup fails and documenting a working debug setup.

Description

Hello.

I'm trying to debug the OpenDebugAD7.exe following the documentation available to gather more information about this extremely annoying performance issue reported in c++ tools extension

However, the attach it's failing when running this with Dotnet extension. I also tried running a GDB with target remote to see if it's able to connect.

  • Connection refused

Config:

{
    "configurations": [
        {
            "name": ".NET Core Attach",
            "type": "coreclr",
            "request": "attach",
            "debugServer": 4711
         }
    ]
}

Tested with different ports with same result.

Environment:

  • WSL Ubuntu 22.04

How I built:

dotnet build src/MIDebugEngine-Unix.sln

./PublishOpenDebugAD7.sh whatever

The thing case is that if I run without --pauseForDebugger, it seems that the port it's accesible and even got connection with GDB.

./OpenDebugAD7.exe --server

imagen

Shouldn't start listening at least and wating for debugger in the port? Or I have misunderstood it?

Related, if I try to attach using the coreclr + OpenDebugAD7 --server --pauseForDebugger, it crashes:

Stopping due to fatal error: FileNotFoundException: Could not find file '/home/borjamf/MIEngine/bin/Debug/vscode/coreclr.ad7Engine.json'.

Could you guide me how to be able to debug this?
Thanks.
