[bobombolo]

actually the first time i opened a file it worked, after that it was broken.

[bobombolo]

i also tried changing the settings.json "dotnetAcquisitionExtension.existingDotnetPath" to /usr/share/dotnet or /usr/lib/dotnet/dotnet to no avail

[dibarbet]

@bobombolo two requests -

1. can you set the dotnet.server.trace configuration to Trace and post the contents of the C# log here?
2. It looks like the process is still active and failing to shutdown, so a process dump here would be useful. The instructions to collect a dump via dotnet-dump are here - https://github.com/dotnet/diagnostics/blob/main/documentation/dotnet-dump-instructions.md#installing-dotnet-dump . Generally it would be dotnet-dump collect --process-id <PID of Microsoft.CodeAnalysis.LanguageServer here> after you install the tool. Can either upload here (if its small enough), or email me (listed in my github profile).

[bobombolo]

owner@navi:~$ dotnet-dump
Required command was not provided.

Usage:
dotnet-dump [options] [command]

Options:
--version Show version information
-?, -h, --help Show help and usage information

Commands:
collect Capture dumps from a process
analyze <dump_path> Starts an interactive shell with debugging commands
to explore a dump
ps Lists the dotnet processes that dumps can be
collected from.

[dibarbet]

The command needs to be run with the following arguments (with the appropriate processid)
dotnet-dump collect --process-id <put the PID of Microsoft.CodeAnalysis.LanguageServer here>

[bobombolo]

i'm sorry i'm so dense but where do i get the PID?

[bobombolo]

i tried ls /proc but it's not there

[dibarbet]

With vscode running and the folder open, you can try
dotnet-dump ps
It should output something like
4148 Microsoft.CodeAnalysis.LanguageServer /home/dibarbet/.vscode/extensions/ms-dotnettools.csharp-2.0.436-linux-x64/.roslyn/Microsoft.CodeAnalysis.LanguageServer ...
where the number at the beggining (4148 for me) is the process id.

If it isn't listed, that means the server isn't running and we'll have to figure out another way to get the information.

[bobombolo]

14301 lysis.LanguageServer lysis.LanguageServer -dotnettools.csharp

this one maybe

[dibarbet]

Yup! That's the one (probably truncated because the window is small).

[bobombolo]

what i get from that when i cat it appears to be a gigantic binary file
