Custom class based DSC resource help

DSC
1

Hi,

I’ve created a custom class based DSC resource and while I don’t see any errors when executing the start-dsc command. The custom resource doesn’t have the intended effect of creating a New-PSDrive.

[DscResource()]

Class CreatePSDrive
{
[DscProperty(Key)]
[string]$Name

[DscProperty(Mandatory)]
[string]$Root

[DscProperty(Mandatory)]
[PSCredential]$Credential

[CreatePSDrive] Get()
{
Write-Verbose $this.Name
Write-Verbose $this.Root

$drive = (Get-PSDrive | ? {$_.Name -eq $this.Name})

if($drive -ne $null)
{
$this.Name = $drive.Name
$this.Root = $drive.Root
}
else
{
$this.Name = $null
$this.Root = $null
}

return $this
}

[void] Set()
{
Write-Verbose $this.Name
Write-Verbose $this.Root
Write-Verbose ($this.Credential).UserName

($this.Name).GetType()

New-PSDrive -Name $this.Name -Root $this.Root -PSProvider FileSystem -Persist -Verbose -Credential $this.Credential
}

[bool] Test()
{
$driveExists = (Get-PSDrive | ? {$_.Name -eq $this.Name})
Write-Verbose $this.Name
Write-Verbose $this.Root

if($driveExists -eq $null)
{
Write-Verbose "PSDrive does not exist"
return $false
}
else
{
Write-Verbose "PSDrive" $this.Name "exists"
return $true
}
}
}

When I’ve run start-dsc I get the following output which indicates the Set ran successfully but when running get-psdrive I cant see the new-psdrive.

If I run the same New-PSdrive command outside of DSC it works fine.

Any pointers you can provide would be greatly appreciated

Thanks
