I'm building a Linux application and debugging it by publishing self-contained executable to the remote target host and attaching Visual Studio debugger.

When I publish it as a single file with this command

dotnet publish  --configuration Debug --runtime linux-x64 --output ./publish --self-contained -p:PublishSingleFile=true 

the debugger fails to connect:

One or more errors occurred.
Failed to attach to process: Failed to load the .NET Debugging Services.

The application can be debugged when it's not self-contained. Is single file debugging possible at all?

• visual-studio-debugging

• Are you attaching to a process on a remote computer(Linux)? – Dou Xu-MSFT Commented Mar 5 at 8:18

• @jackhab not with managed code debugger. You can change the code type to be Native but not sure how good the experience would be – Paweł Łukasik Commented Mar 5 at 17:06
• 1 Yes, I'm connecting via SSH and I'm copying all the content of publish folder. Attaching debugger only fails when I publish as single file. – jackhab Commented Mar 15 at 12:02

No, debugging single file is not supported. See https://github/dotnet/vscode-csharp/wiki/Troubleshoot-loading-the-.NET-Debug-Services.
