NotImplementedException raised when using managed plugin

Unity Engine
1

Hi all!

What I’m trying to do is get the UWF (Universal Write Filter) status in Unity. However, this requires the System.Management namespace, which Mono doesn’t implement. So I compiled a DLL with .NET 4.0, but any time I try to call it, it throws a NotImplementedException. What am I doing wrong?

Here’s the plugin’s full code:

using System;
using System.Management;

namespace UWFTools
{
    public class UWF
    {
        public static string GetUWFStatus()
        {
            ManagementScope scope = new ManagementScope(@"root\standardcimv2\embedded");
            ManagementClass UWFFilter = new ManagementClass(scope.Path.Path, "UWF_Filter", null);
            ManagementClass UWFOverlayConfig = new ManagementClass(scope.Path.Path, "UWF_OverlayConfig", null);
            ManagementClass UWFOverlay = new ManagementClass(scope.Path.Path, "UWF_Overlay", null);
            ManagementClass UWFServicing = new ManagementClass(scope.Path.Path, "UWF_Servicing", null);

            foreach (ManagementObject mo in UWFFilter.GetInstances())
            {
                if (mo.GetPropertyValue("CurrentEnabled").ToString() == "True")
                {
                    return "Enabled";
                }
                else
                {
                    return "Disabled";
                }
            }

            return "Unknown";
        }
    }
}

So I’m thinking the issue is that a DLL can’t use functionality unsupported by Mono either.

I will just pass the UWF status as a command line argument instead.
