I'm using Visual Studio Code, as a code editor for Unity 5.
Visual Studio Code updated itself, after that I found that my C# IntelliSense seems to be broken. It doesn't show suggestions for my classes, it shows only c# syntax suggestions. I've checked all the settings, and logs so everything seems to be correct. There is right workspace settings, OmniSharp is running an no errors in Log. I've tried uninstall/install VSCode but no luck. I can't understand what is the problem, and I need your help.
Any solutions? Screenshots are below.
