Bug Private member unused in Visual Studio

After updating Unity Visual Studio package in Unity, I keep getting this message: "Private member ... is unused" in Visual Studio.

I used the "Regenerate project files" in Unity -> Preferences -> External tools, that helped, until I created a new script within Unity Editor.

Is there any way to report this to Unity team?

 

If I remember correctly they accept regular bug reports and they pass it along to the team who develops the Unity-VS bridge package (Microsoft).

 

I reported it, thanks.
