Is the C# Profiler class available for the Personal edition of Unity?

It seems that the Profiler is available now in the Personal edition of Unity, however VS can’t seem to find
the Profiler C# class.

Since I can’t find any mention of this begin a Pro feature in the documentation I wonder if it is a bug.

UnityEngine.Profiling.Profiler.BeginSample(“some string param”);

Is a perfectly valid line of code in my project. Are you sure you are not using an old Unity version? I checked this using 2018.3.0f2
