VS Code version: 1.29.1

C# Extension version: 1.17.1

mono version: 5.16.0.220

Steps to reproduce

Opening a C# file from Unity project.

Expected behavior

OmniSharp runs as normal. IntelliSense debugs code in real time.

Actual behavior

OmniSharp does not start. The output is as follows:

Starting OmniSharp server at 12/10/2018, 8:56:50 PM
    Target: /Users/Shared/Unity/new_BattleForBFDIBattle/new_BattleForBFDIBattle.sln

OmniSharp server started with Mono 5.16.0.
    Path: /Users/yazid/.vscode/extensions/ms-vscode.csharp-1.17.1/.omnisharp/1.32.8/omnisharp/OmniSharp.exe
    PID: 31933

Cannot open assembly '/Users/yazid/.vscode/extensions/ms-vscode.csharp-1.17.1/.omnisharp/1.32.8/omnisharp/OmniSharp.exe': No such file or directory.
[ERROR] Error: OmniSharp server load timed out. Use the 'omnisharp.projectLoadTimeout' setting to override the default delay (one minute).

It seems that there is no omnisharp.exe installed. I checked for the file by pressing Cmd+Shift+Period in Finder to view hidden files. Here's a picture:

How do you install the omnisharp.exe file? Any help would be appreciated. Thank you for your time.

Well, I guess I found the solution myself..

Solution

1. Uninstall C# extension on VSCode. If Unity Debugger extension blocks you from doing that, uninstall that first.

2. In Finder, delete the entire ms-vscode.csharp-1.17.1 folder in .vscode/extensions/

3. Reinstall C# extension. It will download everything including omnisharp.exe

This has been an easy and somewhat unnecessary, but I hope people who come across the same problem knows what to do. Thank you :)
