Lost On DOTS

I am going through Unity's tutorials on dots and I am having issues with the very first video and Unity 2019.3.0f1.

I have added these 3 packages:
COLLECTIONS
ENTITIES
JOBS

And My code has :

Code (CSharp):

1. using Unity.Entities;

But there is no Game Object Entity Component available. Just "Convert To Entity"

And This Command does not exist:

Code (CSharp):

1. GetEntities<Components>()

This is off Brackey's video on the Unity Learn site, But obviously something has changed since the video was made..

 

Yes the GameObjectEntity workflow has been deprecated. To get started with ECS, You can check out the sample repo which is very helpful: https://github.com/Unity-Technologies/EntityComponentSystemSamples

Also, people has been saying Mike Geig's Unite talk on DOTS is very newcomer-friendly.
