Are you mixing up Visual Studio with VS Code? This pertains to the latter.

Seems so.

Is there no background code analysis in VS code? That would be a reason to switch.

In both VS and VSCode, semantic analysis is handled by specific language extensions (some of which might ship in the box, as C# is in VS and TypeScript is in VSCode). So it's impossible to answer this question without knowing which language you're using.

C#

VSCode uses OmniSharp for that, so at least it's different from VS.

You must have missed the part where it is now 10,000x faster. Given your complaint about performance this should excite you!

If VS is to slow, you need to use out more for the Background code analysis to amortize.

I don't get it.
