How to fullscreen console

Question

I want to fullscreen console as if you would press Alt+Enter. The only thing somewhat close to what I want is something like this, except it maximizes it, not fullscreen.

How would the code for that look?

One of the the answers in the question you linked allows you to maximize the console. Isn't that what you are asking for? If not, why not? — Emond, Mar 05 '18 at 19:40
Fullscreen = no borders, no nothing, only the console. Maximized = borders, everything else, toolbar present. — , Mar 05 '18 at 19:54

Create a console application and use this code: Source and a couple of fixes from me (tested on Windows 10):

using System;
using System.Runtime.InteropServices;

namespace Test
{
    internal class Program
    {
        [DllImport("kernel32.dll")]
        private static extern IntPtr GetStdHandle(int handle);

        private static void Main(string[] args)
        {
            IntPtr hConsole = GetStdHandle(-11);
            SetConsoleDisplayMode(hConsole, 1, out COORD b1);
            Console.ReadLine();
        }

        [DllImport("kernel32.dll", SetLastError = true)]
        private static extern bool SetConsoleDisplayMode(IntPtr ConsoleOutput, uint Flags, out COORD NewScreenBufferDimensions);

        [StructLayout(LayoutKind.Sequential)]
        public struct COORD
        {
            public short X;
            public short Y;

            public COORD(short X, short Y)
            {
                this.X = X;
                this.Y = Y;
            }
        }
    }
}
