Which PowerShell DSC Resources Module To Import

Hello!

These three modules all implement various PowerShell DSC resources:

That gives us three top-level Import-DSCResource lines we could use in configurations (check out this article for an in-context example):

Import-DscResource -ModuleName PSDesiredStateConfiguration
Import-DscResource -ModuleName xPSDesiredStateConfiguration
Import-DscResource -ModuleName PSDscResources

Here are the differences:

Here are my standard practices for which to import:

  1. Start with PSDesiredStateConfiguration.
  2. Upgrade to PSDscResources if you need a feature the built-in module doesn’t have.
  3. Test with xPSDesiredStateConfiguration if things still aren’t working. Avoid using this module in production.

Arguably, it’s a good practice to upgrade to PSDscResources by default. I don’t do that because using the built-in module reduces the number of things I have to install and I like short dependency chains. So far, my use-cases have been simple and the built-in module has been sufficient. Your situation may be different.

Happy configuring!
