And this is an error from eventvwr.msc:
Job {73390701-015C-11EA-A80E-000D3AA83F09} :
This event indicates that a non-terminating error was thrown when DSCEngine was executing Test-TargetResource on xVSTSAgent DSC resource. FullyQualifiedErrorId is NamedParameterNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand. Error Message is A parameter cannot be found that matches parameter name 'Attributes'..

The error is comming from function Get-VstsAgent - line 430

Get-ChildItem "$AgentDirectory**.agent" -Attributes '!D+H,!D' -ErrorAction SilentlyContinue | ...

[jwittner]

Very strange, Get-ChildItem definitely has the Attributes parameter. Even as far back as Version 3.0 of PowerShell. Can I ask what versions of PowerShell you're using, and what your $AgentDirectory is?

[eissko]

I know - that's very strange issue. I would like to put emphasis again on the fact that only 1st cycle of DSC fails. 2nd one is allright. Here below is snippet from DSC configuration - creating volume, the folder and then installing agents in the loop. DependsON should keep the correct flow.

Powershell 5.1 is used

    xDisk CreateDiskVolume
    {
        DiskId = 2
        DriveLetter = "F:"
        DiskIdType = "number"
        FSFormat = "NTFS"
        FSLabel = "agents"
    }

    File CreateFolder {
        Type = 'Directory'
        DestinationPath = 'F:\VSTSAgents\'
        Ensure = "Present"
        DependsOn = "[xDisk]CreateDiskVolume"
    }

    $i=1
    for($i;$i -le $agentCount; $i++){    

            xVSTSAgent "xVSTSAgent $i" {
                Name               = ("{0}{1}" -f "Agent", $i)
                Pool               = $agentPoolName
                ServerUrl          = $ServerUrl
                AccountCredential  = $accountCredential
                AgentDirectory     = "F:\VSTSAgents\"
                Ensure             = "Present"
                PrefixComputerName = $True
                DependsOn          = "[File]CreateFolder"
            }
    }
