Autocompletion for Unity doesn't work

[TriggerEdge]

For some reason autocomplete has stopped working for unity classes. I started having this issue after some unity version 2018.3.6 onwards.

Here is a similar issue but for omnisharp-vim https://github.com/OmniSharp/omnisharp-vim/issues/449

Any solution for this?

I'm having the same issue (on Fedora). This is the output I get when opening an empty C# file (for clarity) in a fresh install with no other plugins (and pressing "Open C# Project" in Unity to generate the solution):

I'm experiencing the same issue on Windows 10, newly installed sublime text and Omnisharp. Does anyone have a fix?

I had a similar issue, just set up a new environment with ST3 + omnisharp + unity, and logs show like working, but it doesn't find usages, or definitions... It is working in my other environment, the difference is just a minor unity bump (2018.4.6 vs 2018.4.12)

Having the same issue on Arch Linux sublime text.

[gustavolsson-ikea]

Same here on OSX 10.15.2 and Unity 2019.3.5

I have a similar issue. My omnisharp server starts fine and autocompletion works for the base C# functions, but not for the unity-specific ones. It should be noted that it works in VSCode, but i really want to use ST3.

Having the same issue on macOS 11.2.3, Sublime Text 3.22, mono 6.12.0.122, Unity 2019.4.19f1c1, I installed Omnisharp from within Sublime Text's package manager.
