It works relatively well, and actually better than in Unity (which use an older C# version), but unfortunately it does not work everywhere. For example, it's not possible to export to the web, which was to me the main show stopper. I needed C# due to some libraries, and I needed that it runs in a browser, so that was game over, no pun intended.
Apart from that, I really preferred Godot over Unity. Faster, more consistent, better learning curve, etc.
