Omnisharp-vscode: C# Extension Stopped Working on Linux

Created on 10 May 2019  路  17Comments  路  Source: OmniSharp/omnisharp-vscode

Issue Description

C# extension stopped working properly on Linux. I've been using this development environment for nearly a year without issues, and today all the sudden it won't work. I see some errors logged in the Omnisharp console, and I cannot navigate through my project by ctrl+clicking on types as I used to be. This is probably due to some component update, but I don't know which.

VSCode also shows a pop up time to time with the error: "Some projects have trouble loading. Please review the output for more details."

I have experienced a similar problem on Linux. Suddenly Omnisharp stopped launching. The output (Log extension Host) show me this info:

As you can see ms-vscode.csharp shows startup:false.

Stopped for me too.

I just upgraded to Ubuntu 19.04 with gnome 3.32.0 - it's 100% due to that. It worked before the upgrade. (Did you guys also recently upgrade?)

Is there a fix?

I think the only thing that I upgrade is vscode to 1.33.1, c# extension to 1.19.X I'm not sure about dotnet.
this is a messss :(

Re-installing mono-devel using the instructions from the mono projects 18.04 section worked for me over on issue 3049 although my Omnisharp warnings and errors logs differed slightly

solrevdev picture solrevdev on 13 May 2019

I fixed my problem - maybe it'll help you. I added the official mono repository, and updated to the latest mono-devel from there.

Same issue here, although it's been the case for a while. Ubuntu 18.04 LTS for me.

The repository is down for me.. it is normal?

dlagg picture dlagg on 13 May 2019

@JorgeDLG No it's not normal, mono is a massively important project. Just try again later, it will work.

lonix1 picture lonix1 on 14 May 2019

I found a way, but it isn't the best solution. In vscode by Pressing Control + K , Control + O , and opening the project folder, omnisharp starts.

dlagg picture dlagg on 14 May 2019

@JorgeDLG I don't understand your problem, but I'm glad you found a way to fix it. In my case I added the mono repository and then installed the latest mono-devel via apt update.

Looks like this issue is similar to https://github.com/OmniSharp/omnisharp-vscode/issues/3049 where a mono update rendered omnisharp unusable. Please try the setting as mentioned above.

I will close this issue for now. Please reopen if it still persists

Hi @akshita31. I tried the above setting but to no avail.I'm getting a different error now though:

@hiranya911 Could you try setting "omnisharp.useGlobalMono": never. This will run omnisharp on the mono that is packed in the omnisharp bits that we ship.

I just upgraded to ubuntu 19.04 and OmniSharp doesnt work anymore until i set the omnisharp.useGlobalMono to never. It worked like a charm

global Mono must be at least 6.4.0, i guess you have an older one
