Windows 2008 R2 and the Windows Management Framework 5
Microsoft’s Desired State Configuration (DSC) overall is a very useful tool. It does, like any product, have some requirements. DSC 5 requires the Windows Management Framework (WMF) 5 be installed before configurations can be deployed to the server. Getting WMF 5 onto Windows Server 2012 R2 is not an issue and requires a simple Windows offline update to be applied. However, Windows Server 2008 R2 (and yes people are still deploying it in an enterprise setting) is not so easy. Windows 2008 R2 WMF 5 requires that both WMF 4 and at least .NET 4.5 be installed prior to upgrading to WMF 5. Luckily both can be installed and then WMF 5 without needing a reboot in between.
Why is this important to The IT Rub? Well build automation, DevOps pipelines and general managment of Windows settings can all be aided by the use of DSC. Therefore, it should be noted that when building automation with a leading orchestration tool, say vRealize Orchestrator, the installation of WMF 5 becomes very important.
Something else to note when discussing WMF 5 is that it includes PowerShell 5. So take heed, when installing WMF 5 you get PowerShell 5 like it or not.
