[UpdateServicesServer] Languages test return false after set

[gbrissard]

Details of the scenario you tried and the problem that is occurring

The issue seems to happen when I try to put more than one language using a string array. It works fine for one language or "*" but as soon as I use an array with multiple languages the following happens :

• No matter if the inital test of the ressource is true or false, it will go for the set script (even if languages are already in the desired state, in which case each language can be seen in the verbose log).

• When the set script is applied, it goes without errors and WSUS configuration is actually changed to the desired language parameter.

• The final test script returns false in any case, making the whole run return in error.

Suggested solution to the issue

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

UpdateServicesServer "WSUS_Service" {
            Ensure                            = "Present"
            ContentDir                        = "F:\WSUS"
            Languages                         = $Languages  # This is a verified string array
            UpdateImprovementProgram          = $false
            SynchronizeAutomatically          = $true
            SynchronizationsPerDay            = 1
            SynchronizeAutomaticallyTimeOfDay = (New-TimeSpan -Hours 0).ToString()
            UpstreamServerName                = "upstream.domain.com"
            UpstreamServerPort                = 8530
            UpstreamServerReplica             = $true
            DependsOn                         = @("[WindowsFeature]WSUS_Feature", "[File]WSUS_Folder")
        }

In the previous DSC log the desired languages are "fr" and "en".
