How about having an internal static property named DefaultPowerShellAppBase like this:
internal static string DefaultPowerShellAppBase { get; } = GetApplicationBase(DefaultPowerShellShellID);And then use this get-only property in places where GetApplicationBase(DefaultPowerShellShellID) is used.

Done.

With that getter-only property, you won't need this method.

This is a bit confusing -- looks like a recursion would happen even though it's not. I suggest removing this if block.

Motivation
We call Utils.GetApplicationBase() multiple times at startup and later so we need cache the one to exclude a reflection.
Fix
DefaultPowerShellAppBaseinUtils.cs.Additional considerations
Code that uses a ShellId from Context has not been changed, although it is only associated with the Windows PowerShell (FullCLR).
