###
### Define the configuration
###
configuration Foo
{
    # One can evaluate expressions to get the node list
    # E.g: $AllNodes.Where("Role -eq Web").NodeName
    node (hostname)
    {
        # Call Resource Provider
        # E.g: WindowsFeature, File
        WindowsFeature XPSViewer
        {
           Ensure = "Present"
           Name   = "XPS-Viewer"
        }
    }
}

###
### Generate the MOF file from the Configuration
###
foo -OutputPath C:\DSC\Foo

###

###
psedit "C:\DSC\Foo\$(hostname).mof"

###
### Process the configuration in the LCM (make it so!)
###
Start-DscConfiguration -Wait -Verbose -Path C:\DSC\Foo -Force

###
