For 3D, use a game engine. Unity, Unreal, maybe Godot depending on your perf requirements.

Thanks. That seems to be the case. My project is currently on top of .NET, so Godot and Stride have been the two I've looked at, although Stride is the only one supporting .NET Core (i.e., .NET 5+). Godot and Unity require Mono still.
