.SYNOPSIS
Install some DSC Resources
.DESCRIPTION
Getting, install, or update DSC Resources I want to have.
It could be used to install every Module from the Gallery.
However, this is something I do with DSC afterwards!
.EXAMPLE
PS C:\> .\invoke-GetDSCResources.ps1
.EXAMPLE
PS C:\> .\invoke-GetDSCResources.ps1 -verbose
VERBOSE: Populating RepositorySourceLocation property for module PSDscResources.
VERBOSE: Try to update PSDscResources
VERBOSE: Updated PSDscResources
.NOTES
Small script I created for myself.
I have to prepare DSC systems from time to time, and I want to have the same set of DSC resources on all of them.
Mainly because I'm lazy, but I'm an old-school Unix guy: Never type something more than two times: AUTOMATE.
I install the resources system wide!
That is why we have the Elevated Shell requirement (#Requires -RunAsAdministrator).
If you want to use it just for the current user, change the Scope in $paramInstallModule from 'AllUsers' to 'CurrentUser'.
