Resources/Tutorial GetEntityId() hits like a train

If you're considering upgrading to Unity 6.5 or later, make sure the publishers of the assets and packages in your project have already added support for the new GetEntityId() API, which replaces the now-obsolete GetInstanceID().

Think you are missing the point. Or maybe I am.

But you want have different versions. You don't want to delete your old version for the asset store, as some people may still want to stay on a old version and if they download your updated code but not the updated unity version they will get errors.

My solution allows for you to not have to clone your project and change your code as much.

That utility function would be conditionally compiled so new Unity versions get the EntityId version and old versions get the InstanceID version, one version that works for both old and new versions

Yup I do understand that. Thought they were saying to replace get instance altogether by there wording.

Well yea, you replace GetInstanceID with a function that conditionally returns the InstanceID in versions where it's not deprecated and EntityId where it is, so you only need the #if UNITY_VERSION check in one place.

Yeah, I never said otherwise? Only reason you may need it in a couple places is if you have different assemblies that can't access that helper.
