PS7 issue with .GetAccessControl() not in .Net Core

[gaelcolas]

This trick does not work with PS7.
The API has changed between .Net 4.x and .net core.

I think the below should work (ok in PS7):

function Get-ACLAccess
{
    [CmdletBinding()]
    param
    (
        [Parameter(Mandatory = $true)]
        [System.String]
        $Path
    )
    $EmptyAcl = [System.Security.AccessControl.DirectorySecurity]::new()
    $ACL = (Get-Acl -Path $Path)
    $ACL.Access.Foreach{$EmptyAcl.Access.AddRule($_)}
    return $ACL
}

Here's how I tested:

$FileSystemAccessRuleProperties = @{
    Path = 'C:\src\testACL'
    Identity = 'AzureAD\GaelColas'
    Rights = @('FullControl')
}

$invokeDscResourceParams = @{
    Name = 'FileSystemAccessRule'
    ModuleName = 'FileSystemDsc'
    Property = $FileSystemAccessRuleProperties
}

if (-not (Invoke-DscResource @invokeDscResourceParams -Method Test).InDesiredState ){
    Invoke-DscResource @invokeDscResourceParams -Method Set -Verbose
}

Invoke-DscResource @invokeDscResourceParams -Method Test
