Failed to launch debug adapter in Visual Studio 2022 – Docker

If I create an ASP Core MVC (Target Framework 5.0) with Docker support enabled and start it I get:

"One or more errors occurred.
Failed to launch debug adapter. Additional information may
available in the output window.
The operation was cancelled."

This is the debug output:

enter image description here

Enabling DebugAdapterHost.Logging with

DebugAdapterHost.Logging /On /OutputWindow

Gives the following output:

1> DebugAdapterHost version: 16.9.50429.2 commit:ca34bde2a8dfef71e1d0b3bafd2804978bfbe6a9

I have tried re-installing Docker Desktop and Visual Studio 2022. Windows 11 is fully updated.

I can build and run an Nginx image directly in Docker Desktop without errors so I think it has something to do with my Visual Studio 2022 install.

My setup:

Docker Desktop 4.5.1

Microsoft Visual Studio Community 2022 (64-bit) – 17.1.0

Windows 11 Home

I also tried downgrading to:

Docker Desktop 4.4.4

Microsoft Visual Studio Community 2019 (64-bit)

But with exactly the same result.

    It turns out that /remote_debugger/vsdbg is indeed missing. It is expected to be found in C:Usersusernamevsdbgvs2017u5 on the host.

    Deleting the whole directory (C:Usersusernamevsdbgvs2017u5) and then pressing F5 forces Visual Studio to re-create the directory and debugging now works.

    For me this worked out:

    1. clean and rebuild the solution.
    2. Disable script debugging in Visual Studio, in the drop-down of green arrow, from where we run the project.

    I got the exact same error "The terminal process terminated with exit code: 4294967295"

    Tried some of the ways

    • Clean/Rebuild

    • Restarted the Visual Studio.

    • Deleting the directory (which was mentioned above)

    • Changed the settings (tools -> options-> Debugging -> General ->enabling the "enable JavaScript debugging" and "multi-target JavaScript debugger"

    I tried some of these links

    VSCodeIssues

    Finally the problem solved by restarting my PC.

    In my case I did a Clean & Rebuild for the project. After this I closed an opened instance of the browser that I used previously to test.

    After this I ran the project and a new instance of the browser opened for testing as usual.

    I was getting the same error message box when trying to use python. For me, enabling native code debugging in the Debug Properties window fixed the issue. You can find Debug Properties under the Debug menu item.

    I also had to download debugging symbols: Microsoft has documentation on how to do so here but the quick run-down is to re-run the python installer, click modify, select both box checkboxes regarding debug symbols, and click Next/Install. Now everything works for me again.

    Enable native code debug checkbox
