I think that I found an answer:
Get-Module will ONLY return the "ExportedCommands" metadata for a Script Module (PSM1) File when the module does not have an associated Manifest (PSD1) File
If you use a Manifest and you want the "ExportedCommands" , you must:
- Comment-Out the "RootModule" from the Manifest File
- Nest the Get-Module command within the Test-Manifest command so that the file returned is a (PSD1) file
Test-ModuleManifest (Get-Module -Name Get-ServerInventory).Path
