Namespace could not be found after installing package via Git in Unity 6.*

[omundy]

I'm surely doing it wrong? I've tried installing via UPM and Git and restarting VS Code and Unity but still the namespace could not be found after installing package via Git in Unity 6.*.

The type or namespace name 'Cysharp' could not be found (are you missing a using directive or an assembly reference?)CS0246

@omundy Maybe try updating it? I had a namespace error to for DoTween WithCancellation an similar. But my scripting definition in player settings had been removed. So just added that again according to the manual here. (using Unity 6000.0.41)
