The IntelliSense worked fine at the beginning when I started the VS code. Sometimes after I used it for a little while, The IntelliSense would lost.
I have two ways to fix this: One is to type the command "Restart Omnisharp" and I will get IntelliSense again. Most of time this way will work, But sometimes it won't. Another way is to close vs code and reopen it. This way worked every time.
I guess the IntelliSense lost usually happened when I write comments in Chinese. But sometimes it didn't happen. I'm not sure.
I'm using C# language. Windows 10. Newest version of Unity and VS code and dotbunny unity tool.

I think I have the same thing.
Omnisharp keeps restarting for me whilst I'm typing (every time I add a new line) - it's very annoying as the lines jump up and down as references are found. Makes VSCode pretty much unusable.

Any suggestions on how to debug this?

Can confirm the same issue with VSCode + C# + Unity. Omnisharp keeps restarting.

This is what I managed to get from embedded developer tools:
https://gist.github.com/BazIdle/df424cb5cd2b065a2618

("potentially unhandled rejected promise" and "Error: Canceled: Error: Canceled" are looping on every Omnisharp restart)

@BazIdle good find. Which Unity version are you on?

Figured a downgrade might fix it. I've tried to find previous versions of vscode for OSX with no joy. Any ideas where to find one?

(The builds on the Wiki are auto-trashed by OSX claiming they're corrupted - so I have to look elsewhere...)

Are you, perchance, getting the same errors in Dev. Tools?

After this and the disastrous Unity update I'm going to have a new rule: Don't download any software updates pushed during December.

All devs are on the egg-nog...

That stack trace is unhappy but won't be the cause of this issue. Can check your omnisharp log (Cmd+L, L) and paste it here?

Here is my omnisharp log. I don't know why there are some strange characters. I'm not using any Chinese characters in the directory names and project names. There are only Chinese characters in comments.

I'm using whichever mono comes with unity 3.5.1f. Version 2.6.5 I think ?

Will downgrading OnmniSharp || VSCode fix this?

@VinditCo Could you try a newer version of mono? Anything above 4.0.1 should be good. Also, what OS are you using?

Just being vocal to let devs know of the spread of the issue.

Same here, omnisharp dies after some time on large (400+ files) project. Omnisharp restart helps sometimes; VSCode restart helps always.

Extensions version 0.3.7; VSCode version 1.0.0; Unity3D 5.3.4; Windows 8.

There's been more some discussion here : dotnet/vscode-csharp#269 (comment)

It seems to be something to do with large projects. Until someone is assigned to fix many of us are having to stick with 0.10.3

@VinditCo I can confirm that it has nothing to do with project size. Intellisense works for me on 1 computer and not on another (both OSX, both same project).
Problem is it just shows 'Loading...' for 10 seconds or more, then it shows Intellisense. Every single time.
Also, I notice references are not shown.

Me too, on both mac and win. Especially coding some playmaker or behavedesigner scrpit, intellisense does need some 20 or 30 seconds to show up. I guess it's due to dlls.. Because other plugins we used in Unity3d are in form of C# scripts, such as NGUI. It works very well.
