  Build    : e8b8861ac7faf042c87a5c2f9f2d04c98b69f28d

VS Code version: 1.19.1 C# Extension version: 1.13.1

Steps to reproduce

Open pre-existing Unity project in VS Code.

Expected behavior

IDE features to work.

Actual behavior

Missing assembly warnings and no IDE features.

The project worked fine a few months ago; I switched to Visual Studio for Mac for a bit but trying to switch back I’ve been hit with this and after all of my attempts to figure out what is going on I have been unsuccessful. I created a brand new project and while I still am getting the same unable to resolve assembly warning intellisense seems to work; it’s just pre-existing projects that seem to be the issue.

Full disclosure in case it is part of the issue; I’m using a compiled omnisharp-roslyn because for some reason the one shipped with the C# extension errors out on my machine.

@rchande seems like it’s not related to the project but rather my machine/vscode/something super strange 😅

I’m on OSX and despite a couple fresh re-installs of the plugin and VSCode the default path the plugin was using was:

OmniSharp server started wth Mono
    Path: /Users/mattbengston/.vscode/extensions/ms-vscode.csharp-1.13.1/.omnisharp/omnisharp/OmniSharp.exe
    PID: 22028

This threw a ton of errors, namely:

System.TypeInitializationException: The type initializer for 'OmniSharp.Utilities.Platform' threw an exception. ---> System.IO.FileNotFoundException: Could not find file "/etc/os-release"
. . .

After comparing the output of a friends editor we noticed that his path was .omnisharp/run, so I updated my settings to:

"omnisharp.path": "/Users/mattbengston/.vscode/extensions/ms-vscode.csharp-1.13.1/.omnisharp/run",

And viola, everything works in every project with no issues.

No idea why it was using OmniSharp.exe vs run, but everything is working perfectly now; so this can probably be closed 😃
