vscode-csharp: LanguageServerProjectSystem throws System.URIFormatException

Type: Bug

Issue Description

VSCode was working just fine for many years until the language
server started failing recently.

When it stopped working I completely removed vscode from my system and deleted all my user data as well.

I then re-installed vscode and for a single session it was working. After a system reboot it stopped working again.

Steps to Reproduce

Open any folder containing a C# project.

Expected Behavior

For it to load normally like before.

Actual Behavior

Error disappears when downgrading to previous version: 2.0.376

This started once I upgraded to the latest extension from a few hours ago 2.0.413.

I can’t load any projects.

I still experience this on v2.0.436 when I use Go to definition.

Got the same error this morning. I solved it by rolling back to v2.0.376

@moander Alright that’s a known limitation then with the v2.0 extension. The fix is on it’s way in https://github.com/dotnet/vscode-csharp/pull/5858, although it’ll still be another week or so since we’ve been prioritizing some other issues at the moment.

jasonmalinowski on Sep 5, 2023

We’ve got a repro here now internally and working on a fix; thanks all for the reports!

jasonmalinowski on Aug 25, 2023

@Cosifne would you help take a look? This is a recent regression.

@lonix1 we are currently releasing fixes every week. September, if there are no blockers will have 4 releases. We do have another release left in August we can catch early next week if we have a fix by then. We will readjust milestone if that spans out.

arkalyanms on Aug 25, 2023

For those, like me, who need this to do their job, I suggest you switch back to Omnisharp for now.
This is the only thing that worked for me. So in other words stick with the current version but enable Omnisharp

(Makes me wonder if we even need something new instead of Omnisharp)

Downgrade to 2.0.376 works for me too. The latest version published to vscode (2.0.413) is not even tagged here.

bjornharrtell on Aug 24, 2023

I have the exact same issue on ubuntu 23.04

koyllis on Aug 24, 2023

Thanks for fixing this quickly! Most stuff kept working, but the constant pop-ups of VSCode that I could not seem to disable, drove me mad. Or arguably just slightly madder.

Same problem. And C# extension is broken again? Maybe you guys should add more test case or hire more QA.

Here’s another example:

mkdir test
cd test
dotnet new console
code .

===================

Reverting to an older version of VSCode (v1.79) does not resolve the issue either.

Switching back to Onmisharp-Server in the settings seems to work (but things are mostly still broken)
