does not work with 2019.3

[jasonswearingen]

I am new to unity and am trying to learn the DOTS workflows,

trying to run this along with the video but it does not build

I installed the latest version of the various dots packages, but still get a lot of build errors

• type ComponentGroup not found
• type ComponentDataWrapper not found (an ecs issue shows this renamed to ComponentDataProxy)
• type EntityArray not found

etc etc etc....

please update the project or give guidence as to what needs to be installed to get this building.
