I have only just found it while looking into Silk.Net (a .Net library that wraps a lot of other graphics libraries). I'm sure it isn't as polished as Unity/Unreal, but it might be equivalent to Godot (which is high praise since Godot is amazing). The fact that it is open-source and supported by the .Net Foundation seems to be the killer feature, so hopefully it will help move people off of Unity who want to stay in a cross platform engine, while still using C#.
