Issue Description

Intellisense doesn't seem to be working correctly, it seems to be missing some classes for C#.for example, I notice when I type the beginning words for the class "Input" it won't autocomplete. I am on Mac os with mono, and net core installed. at first my sln and csproj weren't being generated by Unity, so I had to go to Assets -> open C# file directly, while that generated the sln and csproj files, Intellisense still does not work

Steps to Reproduce

create new project in unity, create new script open script in vs code, try to get autocomplete by typing in "Inpu", however Input class does not appear

Expected Behavior

Type something like "GetComp" or "Inp" and GetComponent<> or Input should autocomplete in

Actual Behavior

Typing in the two classes above does not yield either GetComponent nor Input

Things I've tried

  1. installing mono and setting omnisharp.useGlobalMono to always. For mono I downloaded from here: https://www.mono-project.com/download/stable/ - I downloaded the stable channel version is that the right version for m1 mac?
  2. uninstalling / reinstalling net core sdk 6.0
  3. uninstalling / reinstalling mono
  4. manually setting the path to where dotnet is insalled (file is a sym link, the sym link points to /usr/local/share/dotnet/dotnet) : "omnisharp.dotnetPath": "/usr/local/bin/dotnet"

Logs

dotnet and mono info

  • dotnet (6.0.200): /usr/local/bin/dotnet

Using OmniSharp on global Mono has lower precedence that using .NET 6.0 build of OmniSharp. According to your logs, .NET 6.0 build of OmniSharp is being used.

Make sure to also set "omnisharp.userModernNet": false

I updated my logs to make it shorter and more relevant as well as included everything I've tried so far. I also set userModerNet to false but after I did that the omnisharp fire logo disappear from my tool bar and now intellisense seems to be completely off.

here is my user settings off everything omnisharp related (I removed "omnisharp.dotnetPath")
"omnisharp.useModernNet": false,
"omnisharp.path": "latest",
"omnisharp.useGlobalMono": "always",

According to the logs, the OmniSharp version in use is .omnisharp/1.38.1-beta.72-net6.0 which is the OmniSharp .NET 6.0 build not the Mono one, and that should only come into play when you set "omnisharp.useModernNet": true,. When started with Mono, you would see something like OmniSharp server started with Mono 6.12.0. in the logs and there would be no -net6.0 suffix in the path.

Please double check this setting because I made the typo above (the setting is "omnisharp.useModernNet" not "omnisharp.userModernNet"). "omnisharp.path": "latest" is also not needed because it opts you into the latest OmniSharp prerelease builds which are pulled from the master branch of OmniSharp and can be instable or even broken.

To summarize, you should have the following for unity development on *nix:

"omnisharp.useModernNet": false,
"omnisharp.useGlobalMono": "always"

If it does not help, try keeping the setting "omnisharp.useModernNet": false and re-install the extension, as that should mean OmniSharp would re-acquire its assets.

So upon setting useModernNet to false with useGlobalMono to "always" and even uninstalling and reinstalling c# extension I get an error saying : [ERROR] Error: Unable to find Mono. Ensure that Mono's '/bin' folder is added to your environment's PATH variable.

I've added Mono /bin folder to my PATH here: export ## PATH=$PATH:/Library/Frameworks/Mono.framework/Versions/Current/bin

I found setting useModernNet = false and keeping useGlobalMono = always and deleting the sln and csproj files makes the error log go away, but Intellisense still missing some autocomplete classes. In this case I suspect the sln and csproj files might be the issue but they were auto generated by unity. Should I keep the sln and csproj files? there were more than one csproj but only one sln from what unity generated

setting useModerNet to false and setting useGlobalMono to 'always' omnisharp log

[ERROR] Error: Unable to find Mono. Ensure that Mono's '/bin' folder is added to your environment's PATH variable.

OmniSharp comes in three versions:

  • when you set "omnisharp.useModernNet": true (regardless of other settings), it will run as .NET 6.0 build which supports only .NET Core, .NET 5+ and SDK-style projects which means it will not support Unity development
  • when you set "omnisharp.useModernNet": false and "omnisharp.useGlobalMono": "never", it will run on its own bundled minimal Mono which does not contain .NET Framework reference assemblies. This also means it will not support Unity development
  • when you set "omnisharp.useModernNet": false and "omnisharp.useGlobalMono": "always", it will run on global Mono from your PATH which contains .NET Framework reference assemblies and is the only configuration supporting Unity development.

The extension does not do anything fancy with respect to accessing your PATH - everything is inherited from VS Code, so if something is not visible, the problem likely lies in VS Code itself. However, irrespective of this we have a setting of "omnisharp.monoPath" which, in such situations, can be set to your global Mono installation path, such as /Library/Frameworks/Mono.framework/Versions/Current which should fix it.

/Library/Frameworks/Mono.framework/Versions/Current

ok I have set useModernNet to false and useGlobalMono to always but I am getting [warn]: OmniSharp.CompositionHostBuilder It looks like you have Mono installed which contains a MSBuild lower than 16.10.0 which is the minimum supported by the configured .NET Core Sdk. I downloaded mono 6.12 and even specify vs code to use 16.12 here: "omnisharp.monoPath": "/Library/Frameworks/Mono.framework/Versions/6.12.0", the warning still appears

The warning refers to the version of MSBuild. You should install Mono from the preview channel. MSBuild 16.10 was only introduced in Mono 6.12.0.154 while stable channel is Mono 6.12.0.122.

I downloaded mono 6.12.0 stable version for macos it still gives warning , was that the right version to download? there were only one other version which was 6.12.0 visual studio channel

oh thats what you mean by preview channel, looks like that fixed it - omnisharp appears to work properly now. Thank you!
