        static void Main(string[] args)
        {
            using (PowerShell powerShell = PowerShell.Create())
            {
                powerShell.AddScript("Get-Command");

                Collection<PSObject> results = powerShell.Invoke();

                foreach (PSObject result in results)
                {
                    Console.WriteLine(result.ToString());
