The key part of this command is the GetEnumerator() method because most Azure Cmdlets don’t return an array of individual objects into the pipeline like typical PowerShell cmdlets. Instead returning a System.Collections.Generic.List object, which requires a slight adjustment to the code. This procedure can be used for most Azure Cmdlets to allow the results to be iterated through.
