Question Visual Studio Code unused variables

Hi!
so I started using VS-Code to write my scripts but I'm really missing the feature of fading out unused variables like in Visual Studio and I can't imagine that there is no way to activate it.
The thing is that unused varibales inside of functions do fade out but every variable I declare outside functions do not. In Visual Studio they do.
Maybe somebody know how to fix it?
I only use the C# extension for VS-Code.
I also tried the Roslynator extension and actually with the extension unused variables outside functions are now faded out and underlined but it also underlines to much other stuff I don't want to be underlined like lines that can be simplified or just empty lines to make visual breaks between code parts and this is kindy annoying.
Also I didn't really know where exactly to post that question, so sorry if it is the false sub-forum^^'

 

I'm not 100% sure Visual Code supports that, but I imagine these steps for Visual Studio (converted to work for Visual Code) might make it work:

Also, try update the VSCode package inside of Unity: Window -> Package Manager -> Search for Visual Studio Code Editor -> Press the Update button
