Multiplayer UNet doesn't use UnityEngine.Network anymore right?

I believe the new UNet doesn’t use UnityEngine.Network, and it’s a legacy class, right?

Things like

Network.isServer, Network.isClient

Now should be replaced by NetworkServer and NetworkClient as:

NetworkServer.active, NetworkClient.active

I’m just a bit confused because Unity doesn’t make it as legacy here, as they did for legacy Master Server scripts…

Yes, they most likely forgot to mark it as lagacy. The documentation often “lags behind” the current state. Feel free to file a bug report. there is a category “documentation”.

Idk what do you mean but you need use using UnityEngine.Networking; not UnityEngine.Network!
