VS Code version: 1.17.2
C# Extension version: 1.12.1

Already tried

Updating Mono to latest
Updating OmniSharp
Removing all .csproj and .sln files to get newly generated ones

Steps to reproduce

Open Unity Editor (latest Linux version)
Open C# Project
See errors in output log

Expected behavior

No errors and intellisense to work for Unity 5.

Actual behavior

I get several errors and I don't have any Unity intellisense.

Needs More Info

@badersur I installed Ubuntu 17.10 fresh without updating yea. I using version 1.13.1 extension

I didn't do anything special really.

Installed vscode from https://code.visualstudio.com/Download
Installed mono complete sudo apt-get install mono-complete. I cant remember why I needed that, but i remember it wasn't working and on the mono website it states The package mono-complete should be installed to install everything - this should cover most cases of "assembly not found" errors. So i tried it and it worked.
Installed C# for Visual Studio Code (powered by OmniSharp), Debugger for Unity, Unity Tools, Monobehaviour Snippets in the extensions tab in vscode. (thats pretty much all you need)
Installed vscode asset from Unity Asset Store https://www.assetstore.unity3d.com/en/#!/content/45320. I found I needed this for linux only, didn't need it for windows which was interesting. But it helped point console logs to the correct line in code. Without it, it would only open up the correct file but not point to the correct line. I said above I didn't need it, but I was wrong lol.

That's it, and it works perfectly, I use vscode from work (windows) and from home (linux) with unity with no issues at all. Hope that helped you out.

This looks to me like https://github.com/OmniSharp/omnisharp-vscode/issues/1803. What version of Mono do you have installed?

DustinCampbell on 31 Oct 2017

I had same issue. Unity 2017.2 on Ubuntu 17.10.
Installing sudo apt-get install mono-complete helped me.

FYI: I'm assuming you don't need the VSCode asset anymore. I got it all working without it, on both my windows system and now my Ubuntu system.

Hello @brogan89

May I know which version of the extension you are using? The extension isn't working for me on Ubuntu 17.10! I just see:

Installing C# dependencies...
Platform: linux, x86_64, name=ubuntu, version=17.10

Downloading package 'OmniSharp for Linux (x64)'

Also, did you install a fresh copy of Ubuntu 17.10 without upgrading from an older version? and which version of node are you using?

badersur on 3 Dec 2017

Hello @brogan89. It seems like I can't download the dependencies from https://download.visualstudio.microsoft.com/; the connection times out!

I was able to install the extension from source and utilizing the packages' fallback urls to install them. Sorry for annoying you and have a good day :)

Thank you @brogan89 for you detailed replay :)

It seems like my laptop have some issues when connecting to microsoft's websites! Maybe I'll reinstall Ubuntu and hopefully it'll fix this issue!

I'm not a game developer but I may try unity one day.

badersur on 3 Dec 2017

@badersur in that case you should only need to install ms-vscode.csharp from the extensions. I'm not sure what could hinder the install sorry. It should just work out of the box. Best of luck.

brogan89 on 3 Dec 2017

@brogan89 The extension used to work for me after adding "csharp.fallbackDebuggerLinuxRuntimeId": "ubuntu.16.10-x64" to settings but I faced this issue recently.

I'm used to see similar connection issues while visiting websites using ASP.NET CDN and from nuget! Maybe microsoft doesn't like me. lol :)

Good luck to you, too.

badersur on 3 Dec 2017

same with me.
dotnet project work perfect,but unity can't work

fix by install newest version package from mono office(debian 9 repository)

ywaby on 4 Jan 2018

👍2

@ywaby 's suggestion works well as a temporary solution. I followed the official instructions for adding the Debian 9 repo, followed by

sudo apt-get install mono-complete

This upgraded all existing mono packages on my system and installed a couple of new ones as well. After this, VS Code works like charm with Unity.

However, don't do this, unless you know what you're doing and how this affects your system.

Closing out this older issue, as this sounds like an issue with older mono (as of 2017). Latest mono in 2020 likely doesn't have this same problem, so we'll close it out. If you see this problem with the latest VSCode and latest C# plugin, please ping here and we can investigate.

For future readers, installing extension MSBuild project tools resolved the issue for me.

@cartermp I was having this issue today with VS Code 1.49.2 running on Arch Linux, C# plugin version v1.23.2

dotnet --info output:

No errors showing in Omnisharp log.

Since I did get it working with the MSBuild project tools package I don't personally need more help, but if you want more info I'll be happy to send any logs/etc you need

@cartermp I just freshly installed mono-complete on my ubuntu based distro (PopOS) and I get the following error from a fresh Unity Project with version 2019.4.12f1:

[fail]: OmniSharp.MSBuild.ProjectLoader
The reference assemblies for .NETFramework,Version=v4.7.1 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application. You can download .NET Framework Developer Packs at https://aka.ms/msbuild/developerpacks

I regenerated the unity project files and it is referencing that framework version inside the Assembly-CSharp.csproject file.

Do I need to switch that referenced version, or how can I fix this?

unity 2019.4.12f1
mono 6.8.0.105
.NET core SDK 3.1.403
