Networking components not visible in editor

I am trying to learn multiplayer networking in unity, but when I try to add a Network Manager Component to my empty object, the option doesn't show up. There are no network options to select from. I'm using Unity 2019 and I'm pretty sure that I set up Unity Services correctly. Any ideas?

 

i'm having the same problem.

 

Unet is deprecated and has largely been removed from the editor, and is starting to disappear from the official documentation. It has been moved to a package for those who still want to use it, but you're highly encouraged to choose a 3rd party API at this time instead of Unet.
