IIS Shared Configuration?

[wasabii]

Any interest in this? I have a module as part of my own DSC pack I could contribute. It uses the Enable-IisSharedConfig PowerShell cmdlets to set it up and keep it up to date.

Hi wasabii I'm currently working on a project that requires this functionality. Id be extremely interested in seeing this added :)

I would also be interested in seeing this. We recently deployed our first shared config. Pulling this and centralized cert store into the DSC would be pretty cool.

So, the above worked. But, I'm going to change it up. I'm using Get-IISSharedConfig, Enable-IISSharedCOnfig, etc. These commands are available only on 2016, apparently.

Any updated on this one?

[johlju]

I labeled this as resource proposal and help wanted so that someone in the community can ran with this.
