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:

Enabling DebugAdapterHost.Logging with

DebugAdapterHost.Logging /On /OutputWindow

Gives the following output:

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.

CodePudding user response：

It turns out that /remote_debugger/vsdbg is indeed missing. It is expected to be found in C:\Users\username\vsdbg\vs2017u5 on the host.

Deleting the whole directory (C:\Users\username\vsdbg\vs2017u5) and then pressing F5 forces Visual Studio to re-create the directory and debugging now works.

CodePudding user response：

For me this worked out:

1. By cleaning and rebuild the solution.
2. By disabling script debugging in Visual Studio, in the drop down of Green Arrow, from where we run the project.
