Cannot access winsat data from WWI using c#

Question

I am trying to access winsat data . WMI has a class for it .

Win32_WinSAT

I am trying to get that recent data using query

"SELECT * FROM Win32_WinSAT WHERE TimeTaken='MostRecentAssessment'"

It will work fine in PowerShell and even in WMIExplorer But it is not working in C# code using System.Management class

My code is as follows

class WinSatData
    {
        public double MemoryScore { get; set; }
        public double CPUScore { get; set; }
        public double D3DScore { get; set; }
        public double DiskScore { get; set; }
        public double GraphicsScore { get; set; }
    }
class Program
    {
        static void Main(string[] args)
        {
            List<WinSatData> winsat = new List<WinSatData>();
            ManagementScope scope = new ManagementScope("\\\\localhost\\root\\cimv2");
            scope.Connect();

            ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_WinSAT WHERE TimeTaken='MostRecentAssessment'");
            ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
            ManagementObjectCollection collection = searcher.Get();

            foreach (ManagementObject m in collection) {
                WinSatData win = new WinSatData();
                win.CPUScore = (Convert.ToDouble(m["CPUScore"]));
                win.MemoryScore = (Convert.ToDouble(m["MemoryScore"]));
                win.D3DScore = (Convert.ToDouble(m["D3DScore"]));
                win.GraphicsScore = (Convert.ToDouble(m["GraphicsScore"]));
                winsat.Add(win);
            }
            string outout = JsonConvert.SerializeObject(winsat);
            Console.WriteLine(outout);
            Console.ReadKey();
        }
    }

All the values in the Management object are zero . I carefully went through the properties of ManagementObject m . Property name is right but value is wrong.

Output is as follows:

[{"MemoryScore":0.0,"CPUScore":0.0,"D3DScore":0.0,"DiskScore":0.0,"GraphicsScore":0.0}]

Please help me access WinSAT.
