Windows Management Framework 5.0 February preview available

Windows PowerShell team announced the availability of Windows Management Framework (WMF) 5.0 Preview February 2015. This preview is available for Windows 8.1, Windows Server 2012 R2, and Windows Server 2012.

As announced earlier, this WMF release continues to include both stable and experimental features. I mean a lot of them! 🙂

Scenario Design Status

Remove DSC documents delivered to a system Stable
Support for inheritance with classes in Windows PowerShell Experimental

Audit Windows PowerShell usage by transcription and logging Stable
Interact with symbolic links using improved Item cmdlets Stable
Network Switch management with Windows PowerShell Stable
DSC authoring improvements in Windows PowerShell ISE Stable

From a DSC point of view, there are many improvements.

Class-defined DSC resource authoring is improved and there are subtle changes that are required for the old class-defined resource, if you built any.

A new RefreshMode in DSC called disabled lets 3rd party configuration managers such as Chef manage a node configuration using their own agent or using the Invoke-DscResource cmdlet which means we would be able to do this directly using the CIM method as well. More on this later.

Partial configurations now support mixed refresh modes including Push and Disabled. Partial configurations are great way to enable delegated configuration authoring and management.

DSC resource script debugging is a great addition and my subsequent posts will talk about this.

Go ahead and start exploring WMF 5.0.
