[EthanLin0224]

I'm using Unity 2019.2.17f1 ,and xrfoundation 3.1.0...installed,
but this asset I opened, then console show -->
The type or namespace name 'ARReferencePointManager' could not be found (are you missing a using directive or an assembly reference?) [Assembly-CSharp]csharp(CS0246)
why does it?
