runtime: Process.VirtualMemorySize64 (at least) is giving corrupt values

System.Diagnostics.Process.VirtualMemorySize64 has an unexpected High Value (Windows 10 x64)

Example:

using System;
class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("VirtualMemorySize:{0:#,0.}", System.Diagnostics.Process.GetCurrentProcess().VirtualMemorySize64);
        Console.ReadKey();
    }
}

Output: VirtualMemorySize:2.199.520.038.912 Expected output : <= 150 MB as with .NET Classic
