Answer 1

If you want to hide the Console App from App(s) list in Task Manager

Try this :

using System;
using System.Runtime.InteropServices;

namespace SampleConsoleTest
{
    class Program
    {

        [DllImport("kernel32.dll")]
        static extern IntPtr GetConsoleWindow();


        [DllImport("user32.dll")]
        static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);


        const int SW_HIDE = 0;
        const int SW_SHOW = 5;

        static void Main(string[] args)
        {
            var handle = GetConsoleWindow();


            // Hide
            ShowWindow(handle, SW_HIDE);


            // Show
            //ShowWindow(handle, SW_SHOW);

            Console.ReadKey();
        }
    }
}

This does not show the app in App List, but is visible in process(s) list.
