How to get ram, cpu, disk data from hyper-v with WMI

private static void Main(string[] args)
        {
            //can you add try catch to this code
            try
            {
                string vmName = "windows1";  // Replace with your VM name
                ManagementScope scope = new ManagementScope(@"\\.\ROOT\virtualization\v2");

                // Query for the virtual machine
                ObjectQuery query = new ObjectQuery(string.Format("SELECT * FROM Msvm_ComputerSystem WHERE ElementName = '{0}'", vmName));

                // Execute the query
                using ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
                foreach (ManagementObject queryObj in searcher.Get())
                {
                    // Get the memory
                    Console.WriteLine("Memory: {0}", queryObj["TotalMemory"]);

                    // Get the disks
                    using ManagementObjectCollection relatedDisks = queryObj.GetRelated("Msvm_VirtualHardDisk");
                    foreach (ManagementObject disk in relatedDisks)
                    {
                        Console.WriteLine("Disk path: {0}", disk["Path"]);
                    }
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
                throw;
            }
        }

But I am getting invalid namespace, how can I fix this?
