Which feature was first included by default in PowerShell version 5?


EXPLANATION

New features in Windows PowerShell Desired State Configuration

  • Windows PowerShell language enhancements let you define Windows PowerShell Desired State Configuration (DSC) resources by using classes. Import-DscResource is now a true dynamic keyword; Windows PowerShell parses the specified module’s root module, searching for classes that contain the DscResource attribute. You can now use classes to define DSC resources, in which neither a MOF file nor a DSCResource subfolder in the module folder is required. A Windows PowerShell module file can contain multiple DSC resource classes.
  • A new parameter, ThrottleLimit, has been added to the following cmdlets in the PSDesiredStateConfiguration module. Add the ThrottleLimit parameter to specify the number of target computers or devices on which you want the command to work at the same time.
    • Get-DscConfiguration
    • Get-DscConfigurationStatus
    • Get-DscLocalConfigurationManager
    • Restore-DscConfiguration
    • Test-DscConfiguration
    • Compare-DscConfiguration
    • Publish-DscConfiguration
    • Set-DscLocalConfigurationManager
    • Start-DscConfiguration
    • Update-DscConfiguration
  • With centralized DSC error reporting, rich error information is not only logged in the event log, but it can be sent to a central location for later analysis. You can use this central location to store DSC configuration errors that have occurred for any server in their environment. After the report server is defined in the meta-configuration, all errors are sent to the report server, and then stored in a database. You can set up this functionality regardless of whether or not a target node is configured to pull configurations from a pull server.
  • Improvements to Windows PowerShell ISE ease DSC resource authoring. You can now do the following.
    • List all DSC resources within a configuration or node block by entering Ctrl+Space on a blank line within the block.
    • Automatic completion on resource properties of the enumeration type.
    • Automatic completion on the DependsOn property of DSC resources, based on other resource instances in the configuration.
    • Improved tab completion of resource property values.
  • A new DscLocalConfigurationManager attribute designates a configuration block as a meta-configuration, which is used to configure the DSC Local Configuration Manager. This attribute restricts a configuration to containing only items which configure the DSC Local Configuration Manager. During processing, this configuration generates a *.meta.mof file that is then sent to the appropriate target nodes by running the Set-DscLocalConfigurationManager cmdlet.
  • Partial configurations are now allowed in Windows PowerShell 5.0. You can deliver configuration documents to a node in fragments. For a node to receive multiple fragments of a configuration document, the node’s Local Configuration Manager must be first set to specify the expected fragments
  • Cross-computer synchronization is new in DSC in Windows PowerShell 5.0. By using the built-in WaitFor* resources (WaitForAll, WaitForAny, and WaitForSome), you can now specify dependencies across computers during configuration runs, without external orchestrations. These resources provide node-to-node synchronization by using CIM connections over the WS-Man protocol. A configuration can wait for another computer’s specific resource state to change.
  • Just Enough Administration (JEA), a new delegation security feature, leverages DSC and Windows PowerShell constrained runspaces to help secure enterprises from data loss or compromise by employees, whether intentional or unintentional. For more information about JEA, including where you can download the xJEA DSC resource, seeJust Enough Administration, Step by Step.
  • The following new cmdlets have been added to the PSDesiredStateConfiguration module.
    • A new Get-DscConfigurationStatus cmdlet gets high-level information about configuration status from a target node. You can obtain the status of the last, or of all configurations.
    • A new Compare-DscConfiguration cmdlet compares a specified configuration with the actual state of one or more target nodes.
    • A new Publish-DscConfiguration cmdlet copies a configuration MOF file to a target node, but does not apply the configuration. The configuration is applied during the next consistency pass, or when you run the Update-DscConfiguration cmdlet.
    • A new Test-DscConfiguration cmdlet lets you verify that a resulting configuration matches the desired configuration, returning either True if the configuration matches the desired configuration, or False if the actual configuration does not match the desired configuration.
    • A new Update-DscConfiguration cmdlet forces a configuration to be processed. If the Local Configuration Manager is in pull mode, the cmdlet gets the configuration from the pull server before applying it.
