This appears to be a bug in the unity.entities package 1.2.x. They seem to have overlooked SystemAPI.ManagedAPI.GetComponentTypeHandle and using it currently causes a compile error. However if you replace those calls with EntityManager.GetComponentTypeHandle it works fine.

Opened a PR with the fix.
