vscode-csharp: OmniSharp stopped working after update to 1.19.0

Issue Description

After installing V1.19.0 of the C# extension, Omnisharp has stopped working in all my workspaces.

When looking at the Omnisharp log there are no visible errors, but it always seem to get stuck after the first Adding project ..../.../Project.csproj, no timeout or anything else comes after some time waiting.

I checked my .Net runtime version and it’s 4.7.2 (461814)

Steps to Reproduce

Update 1.19.0 of the C# Extension was automatically installed by VSCode.

Expected Behavior

Omnisharp and intellisense should keep working normally.

Actual Behavior

Omnisharp does not load anymore.

@iSazonov FYI. I was able to downgrade using the built-in option in VSCode, right click on extension and “Install another version…”

Exact same problem with ms-vscode.csharp 1.19.0 on Windows 10 .NET 4.7.2 (46184).

(Only a downgrade to 1.18 works…)

Changing (for me INCLUDING) "omnisharp.path": "1.32.19-beta.25" in settings.json, solved problem. Thank you @filipw

Using "omnisharp.path": "1.32.19-beta.25", reloading Omnisharp, reloading window and waiting a bit seems to have done the trick. No global Mono required.

Thanks a lot for the log!

Could you please double check if you have "omnisharp.path": "1.32.19-beta.25" set in the VS Code settings (and after that restart VS Code)? What I can see in your log is that the version 1.32.18 (which is bundled with extension 1.19.0) gets started instead (notice the path to omnisharp in the folder name).

Starting OmniSharp server at 4/25/2019, 4:52:10 PM
    Target: /Users/jmarin/DockerVolume/projects/myproject/My.Project.sln

OmniSharp server started.
    Path: /Users/jmarin/.vscode/extensions/ms-vscode.csharp-1.19.0/.omnisharp/1.32.18/run
    PID: 88031

It should be something like this:

Starting OmniSharp server at 4/25/2019, 5:58:05 PM
    Target: /Users/filip/Documents/dev/test-wildcard

OmniSharp server started with Mono 5.18.1.
    Path: /Users/filip/.vscode/extensions/ms-vscode.csharp-1.19.0/.omnisharp/1.32.19-beta.25/omnisharp/OmniSharp.exe
    PID: 39989

If you navigate to /Users/{username}/.vscode/extensions/ms-vscode.csharp-1.19.0/.omnisharp you should see all OmniSharp version that you have available locally.

One other thing worth trying out (if 1.32.19-beta.25 still doesn’t help you) is to install global Mono from here https://www.mono-project.com/download/stable/ (the latest stable is 5.20.1). OmniSharp will prefer to use global Mono over the one that is bundled with OmniSharp and that often helps with some more complicated project setups.

Hope this helps.

This looks very similar to this https://github.com/OmniSharp/omnisharp-vscode/issues/3009#issuecomment-484772057 could you please try with the solution explained in that comment? thanks!

I’m a similar (if not the same) issue. Upgrading to the 1.32.19-rc25 build of Omnisharp didn’t fix it for me. Instead, I installed the 1.19.0 version of omnisharp-vscode from the Marketplace, and downgraded omnisharp.path to 1.32.11, which I believe is the version of omnisharp-roslyn baked into 1.18.0 of omnisharp-vscode.

The change to omnisharp.path is the only setting I’ve changed from the default, latest install.
