How do I obtain the current Windows DSC working folder (ie. "\DSC.0")?

Question

Anyone know how to obtain the current DSC working folder?

On the server, when DSC runs, it generates a folder stucture like the following:

C:\Packages\Plugins\Microsoft.Powershell.DSC\2.18.0.0\DSCWork\DSC.0

The only trouble is when DSC gets a new version, it increments the ".X" folder.. However, when DSC runs, there is no clear way how to resolve the current folder from a script block predictably:

    Script GetDscCurrentPath
    {
        TestScript = {
            return $false
        }
        SetScript ={
            Write-Verbose (Get-Item 'C:\%path_to_dsc%\FileInsideMyDscAsset.txt')
        }
        GetScript = { @{Result = "GetDscCurrentPath"} }
    }

Thoughts? Thanks in advance!!!

The DSC Extension does not expose a variable or function to get the current working directory, but since your script / module is in the directory you should be able to use the PSScriptRoot to get the directory. Here is an example:

Write-Verbose -Message "PSScriptRoot: $PSScriptRoot" -Verbose

# Note PSScriptRoot will change when the extension executes
# your configuration function.  So, you need to save the value 
# when your configuration is loaded
$DscWorkingFolder = $PSScriptRoot

configuration foo {

    Script GetDscCurrentPath
    {
        TestScript = {
            return $false
        }
        SetScript ={
            Write-Verbose $using:DscWorkingFolder
        }
        GetScript = { @{Result = $using:DscWorkingFolder} }
    }
}
