I'm building a Linux .net 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?
No, debugging single file is not supported. See https://github.com/dotnet/vscode-csharp/wiki/Troubleshoot-loading-the-.NET-Debug-Services.
