Unable to build MOF to set the RDS-Licensing Role and RDS-Gateway role on the same server,

The DSC configuration that is used to reproduce the issue (as detailed as possible)

    XRDServer LicenseServer
    {
        ConnectionBroker = $localhost
        Server = $localhost
        Role = 'RDS-Licensing'
    }

    XRDServer GatewayServer
    {
        ConnectionBroker = $localhost
        Server = $localhost
        Role = 'RDS-Gateway'
        GatewayExternalFqdn = $GatewayExternalFqdn
    }

Suggested solution to the issue

I suggest that these two configurations shouldn't be conflicting.

The operating system the target node is running

Version of the DSC module that was used ('dev' if using current dev branch)

Current

Just ran into this as well. It looks like the xRDServer resource is keyed on Server alone, so no two blocks with the same server are allowed.

I believe the fix for this is to key instead on Server and Role, so you can have as many blocks as there are unique combinations of those two properties. I am testing this out now and will submit a PR if it works.
