There are a couple of built-in resources that can be used out of the box. You can enumerate them on a plain system with Get-DscResource:
| Windows (Get-DscResource -Module PSDesiredStateConfiguration) | Linux (Get-DscResource -Module nx) |
| File | nxFile |
| Archive | nxArchive |
| Environment | nxEnvironment |
| Group | nxGroup |
| Log | |
| Package | nxPackage |
| Registry | |
| Script | nxScript |
| Service | nxService |
| User | nxUser |
| WindowsFeature | |
| WindowsPackageCab | |
| WindowsProcess | |
| nxSshAuthorizedKeys |
Additionally, there are several set resources that can create multiple instances of one resource, for example, ServiceSet, as well as the WaitFor* resources, which can be used to wait for configurations of other nodes to converge.
