Export hyperV virtual machine using C# on Visual Studio 2022

Question

Hi , 

I'm trying to write a small utility to export a virtual machine on Windows hyperV. I tried this program using Visual studio 2002 and select Console app / .net framework 4.8. I found this example microsoft website. 

Here is the link:   learn.microsoft.com/en-gb/previous-versions/windows/desktop/virtual/msvm-virtualsystemmanagementservice-exportvirtualsystemex

I cannot get anything under Utility.GetServiceObject or Utility.GetTargetComputer(vmName, scope). 

Any help will be highly appriciated. 

Following is the full code from MS: 

using System;
using System.IO;
using System.Management;

namespace HyperVSamples
{
    class ExportVirtualSystemExClass
    {
        static string GetVirtualSystemExportSettingDataInstance(ManagementScope scope)
        {
            ManagementPath settingPath = new ManagementPath("Msvm_VirtualSystemExportSettingData");

            ManagementClass exportSettingDataClass = new ManagementClass(scope, settingPath, null);
            ManagementObject exportSettingData = exportSettingDataClass.CreateInstance();

            exportSettingData["CopySnapshotConfiguration"] = 0;
            exportSettingData["CopyVmRuntimeInformation"] = true;
            exportSettingData["CopyVmStorage"] = true;
            exportSettingData["CreateVmExportSubdirectory"] = true;

            string settingData = exportSettingData.GetText(TextFormat.CimDtd20);

            exportSettingData.Dispose();
            exportSettingDataClass.Dispose();

            return settingData;
        }


        static void ExportVirtualSystemEx(string vmName, string exportDirectory)
        {
            ManagementScope scope = new ManagementScope(@"root\virtualization", null);
            ManagementObject virtualSystemService = Utility.GetServiceObject(scope, "Msvm_VirtualSystemManagementService");

            ManagementBaseObject inParams = virtualSystemService.GetMethodParameters("ExportVirtualSystemEx");

            ManagementObject vm = Utility.GetTargetComputer(vmName, scope);
            inParams["ComputerSystem"] = vm.Path.Path;
            
            if (!Directory.Exists(exportDirectory))
            {
                Directory.CreateDirectory(exportDirectory);
            }
            inParams["ExportDirectory"] = exportDirectory;
            inParams["ExportSettingData"] = GetVirtualSystemExportSettingDataInstance(scope);

            ManagementBaseObject outParams = virtualSystemService.InvokeMethod("ExportVirtualSystemEx", inParams, null);

            if ((UInt32)outParams["ReturnValue"] == ReturnCode.Started)
            {
                if (Utility.JobCompleted(outParams, scope))
                {
                    Console.WriteLine("VM '{0}' were exported successfully.", vm["ElementName"]);

                }
                else
                {
                    Console.WriteLine("Failed to export VM");
                }
            }
            else if ((UInt32)outParams["ReturnValue"] == ReturnCode.Completed)
            {
                Console.WriteLine("VM '{0}' were exported successfully.", vm["ElementName"]);
            }
            else
            {
                Console.WriteLine("Export virtual system failed with error:{0}", outParams["ReturnValue"]);
            }

            inParams.Dispose();
            outParams.Dispose();
            vm.Dispose();
            virtualSystemService.Dispose();
        }

        static void Main(string[] args)
        {
            if (args != null && args.Length != 2)
            {
                Console.WriteLine("Usage: ExportVirtualSystemEx vmName exportDirectory");
                return;
            }
            ExportVirtualSystemEx(args[0], args[1]);
        }
    }
}
