Using a Custom class 5 DSCresource multiple times in a Configuration

DSC
#1

Hi

Using Server 2012R2 with WMF 5
I have written a DSCresource in Class 5 style for installing SharePoint 2013 updates.

When I try to compile-to-mof using this dscresource in my configuration mutliple times for deploying different patches I get errors like the following:

Test-ConflictingResources : A conflict was detected between resources '[InstallSharePointUpdate]SharePointSP1 (::441::9::InstallSharePointUpdate)' and '[InstallSharePointUpdate]SharePointSP1LanguagePackUpdate (::451::9::InstallSharePointUpdate)' in node 'vm11'. Resources have identical key properties but there are differences in the following non-key properties: 'PatchFileName'. Values 'officeserversp2013-kb2880552-fullfile-x64-en-us.exe' don't match values 'serverlpksp2013-kb2880554-fullfile-x64-nb-no.exe'. Please upd
ate these property values so that they are identical in both cases.

In the Configuration they look like this:

# Install SharePoint 2013 SP 1
        InstallSharePointUpdate SharePointSP1
        {
            PathtoFile = $ConfigurationData.NonNodeData.SharePoint.Binaries.Updates
            PatchFileName = 'officeserversp2013-kb2880552-fullfile-x64-en-us.exe'
            Ensure = "Present"
            PsDscRunAsCredential = $SPSetupCred  
            DependsOn = "[InstallSharePointLanguagePack]NoLAnguagePack"      
        }
 
        # Install Norwegian Language pack for SharePoint 2013 SP 1
        InstallSharePointUpdate SharePointSP1LanguagePackUpdate
        {
            PathtoFile = $ConfigurationData.NonNodeData.SharePoint.Binaries.Updates
            PatchFileName = 'serverlpksp2013-kb2880554-fullfile-x64-nb-no.exe'
            Ensure = "Present"          
            PsDscRunAsCredential = $SPSetupCred   
            DependsOn = "[InstallSharePointUpdate]SharePointSP1"     
        }
 
        # Install SharePoint 2013 CU April 2016
        InstallSharePointUpdate SharePointAprilCU2016
        {
            PathtoFile = $ConfigurationData.NonNodeData.SharePoint.Binaries.Updates
            PatchFileName = 'ubersrv2013-kb3114938-fullfile-x64-glb.exe'
            Ensure = "Present"          
            PsDscRunAsCredential = $SPSetupCred   
            DependsOn = "[InstallSharePointUpdate]SharePointSP1LanguagePackUpdate"     
        }

How can i change this dscresource so that it will let me reuse it installing different patches?

What does work is creating dupicate classes with new names and running one update per dscresource. But that seems like waste of space:P…

Any tips are welcome!

In your class-based resource, what property have you defined as the key?

Your class needs to be designed so that every instance of it in a configuration can have a unique key. That isn’t the case, which is why PowerShell’s upset.
