Steps to reproduce

Create a Unity 2D project
Set code to be External Script Editor
- Go to Edit > Preferences.
  - Go to External Tools tab and change the External Script Editor using the Browse... option
    - Select /usr/bin/code/
Back in Unity, create a C# script asset
Double click on script

Expected behavior

C# Intellisense to work.

Actual behavior

C# Intellisense doesn't work. Here is my OmniSharp Log output:

DustinCampbell · 2017-11-08T20:22:34Z

Thanks for all of the detail. I'm creating a VM right now to take a look.

dhicksNTIA · 2017-11-08T20:24:58Z

@DustinCampbell Great! I honestly think it has something to do with the .sln or the .csproj files that Unity generates, but I can't be sure.

DustinCampbell · 2017-11-08T20:25:32Z

One thing to quickly check -- could you list the contents of /home/dhicks/.vscode/extensions and let me know if there are multiple ms-vscode.csharp versions or just a single one.

dhicksNTIA · 2017-11-08T20:27:46Z

$ ls ~/.vscode/extensions | grep csharp
ms-vscode.csharp-1.13.0

DustinCampbell · 2017-11-08T20:30:32Z

Thanks I've seen situations where old extension versions where left behind and loaded incorrectly by VS Code.

DustinCampbell · 2017-11-08T20:38:13Z

Another thing to check: does the file, /usr/lib/mono/msbuild/15.0/bin/Microsoft.Build.dll exist?

DustinCampbell · 2017-11-08T20:38:36Z

Also, which mono package did you install? mono-devel?

dhicksNTIA · 2017-11-08T20:44:50Z

$ ls -a /usr/bin/mono/msbuild/15.0/bin
.  ..  Roslyn

Microsoft.Build.dll doesn't exists :/ I installed both mono-devel and mono-complete. Here is the output of the Roslyn folder:

$ ls -a /usr/bin/mono/msbuild/15.0/bin/Roslyn
.               csi.rsp                                      Microsoft.CodeAnalysis.dll            System.Collections.Immutable.dll
..              Microsoft.Build.Tasks.CodeAnalysis.dll       Microsoft.CodeAnalysis.Scripting.dll  System.Reflection.Metadata.dll

csi.exe.config  Microsoft.CodeAnalysis.CSharp.Scripting.dll  Microsoft.VisualBasic.Core.targets    VBCSCompiler.exe.config

DustinCampbell · 2017-11-08T20:48:16Z

Hmmm... it seems that Microsoft.Build.dll simply doesn't exist. That's very strange if you installed both mono-devel and mono-complete. However, that would also explain the problem. I would also assume that running msbuild at the command-line would fail.

I believe there's a separate msbuild package for Debian environments that Mono provides. I would have expected it to be installed with the mono packages you installed, but maybe there's an issue. Try installing msbuild via apt-get.

dhicksNTIA · 2017-11-08T20:49:56Z

It is super weird, I agree. No idea what happened. Okay, I ran sudo apt install msbuild.

That seemed to do the trick! A+

dhicksNTIA · 2017-11-08T20:52:07Z

You can definitely close the issue. Thanks, @DustinCampbell, you're the best.

DustinCampbell · 2017-11-08T20:56:25Z

Great! Thanks for the heads up. I'm going to file an issue over in omnisharp-roslyn to make sure we fix this appropriately.

DustinCampbell · 2017-11-08T23:10:51Z

I filed OmniSharp/omnisharp-roslyn#1011 to improve OmniSharp when the msbuild package is not installed.
