Azure Resource Manager and Powershell DSC - changes not being applied

Question

I have an ARM template with a Powershell DSC extension section running the following DSC:

Configuration Name
{
    Node MachineName
    {
        #IIS Role
        WindowsFeature IIS
        {
            Name = “Web-Server”
            Ensure = “Present”
        }

        #IIS GUI
        WindowsFeature WebServerManagementConsole
        {
            Name = "Web-Mgmt-Console"
            Ensure = "Present"
        }
    }
}

This runs fine and as expected. The problem occurs if I try to change anything (e.g. add a new WindowsFeature or change an Ensure option to "Absent"). These changes are not reflected on the server.

Is there a flag or option to enable ARM to push DSC changes to the server?

Yeah, the DSC extension does not apply changes to existing machines with previous versions of your DSC templates. The only way I have been able to get this to work is to delete the DSC extension and then re-run the ARM template to re-apply it, with your changes.

This is not the case if you use the Azure Automation pull server (so pull instead of push) this will pull new changes.
