Most of the samples (https://github.com/Unity-Technologies/EntityComponentSystemSamples) should slowly be switching over to it.

If you wanna get started:

As an example here is a simple PlayerName Aspect:
https://github.com/Unity-Technologies/ECS-Network-Racing-Sample/blob/master/Assets/Scripts/Components/Player.cs#L28-L33
Further down there's also other player aspects, one of which you can see an example of here:
https://github.com/Unity-Technologies/ECS-Network-Racing-Sample/blob/master/Assets/Scripts/Gameplay/Race/PlayerProgressSystem.cs#L82-L113
A simple job that checks current player status and updates some checkpoint info if needed.
