Syntax Correction/Highlighting has Vanished in VSC

[NinjaNezumi]

HI everyone!

So, apparently OmniSharp broke, I don't know why or how, and it took me a half dozen uninstalls and reinstalls. At one point I accidentally installed x86 dotnet. Well, I also installed and reinstalled the main version of VS.

Whatever happened, it now works.

Issue Description

As of 1 week ago (or so) my VSC stopped showing syntax issues with my code. The red wavy lines disappeared. I am in the middle of programming a game in Unity 3D and using VSC to do it.

Steps to Reproduce

It just won't show errors in my code as being errors.

Expected Behavior

When I mistype code, like this:

pubblic int variable;

I expect pubblic to have wavy red lines under it.

Actual Behavior

But VSC stopped doing wavy lines under mistyped code a week ago.

I don't know if I accidentally hit a button or not.

I use unity to create game apps and VSCode is constantly loosisng intellisence. Please fix a stable solution to not have to constantly search for workarounds, or anounce that VSCode should not be used with unity!!

Since version 1.25.0 the extension moved by default to .NET 6.0 build of Omnisharp. For Unity development (see #5120 (comment) for more details) you have to set the omnisharp.useModernNet option to false.
