A quick and dirty hack to run chrome in Fullscreen (Kiosk) mode

ChromeKioskRunner.cs

using System;
using System.Runtime.InteropServices;
using System.Diagnostics;

namespace ChromeKioskRunner
{
    class Program
    {
        private const uint WM_KEYDOWN = 0x100;
        private const int VK_F11 = 0x7A;

        [DllImport( "user32.dll" )]
        static extern IntPtr GetForegroundWindow();

        [DllImport( "user32.dll" )]
        private static extern IntPtr SendMessage( IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam );

        [DllImport( "user32.dll" )]
        [return: MarshalAs( UnmanagedType.Bool )]
        static extern bool IsWindow( IntPtr hWnd );

        static void Main( string[] args )
        {
            string program = @"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe";
            string defaultOptions = @"--new-window ";
            string combinedArgs = defaultOptions + string.Join( " ", args );

            var process = Process.Start( program, combinedArgs );

            // Wait and get the foreground window
            // hopefully nothing interups the process start...
            System.Threading.Thread.Sleep( 500 );            
            IntPtr activeWindowHandle = GetForegroundWindow();

            // Send F11 keystroke (i.e. fullscreen hotkey)
            SendMessage( activeWindowHandle,
                         WM_KEYDOWN,
                         new IntPtr( VK_F11 ),
                         new IntPtr( 0x0 ) );

            // Wait for the window to close before returning
            while( IsWindow( activeWindowHandle ) )
            {
                System.Threading.Thread.Sleep( 1000 );
            }
        }
    }
}

Needed that to start Netflix and Crunchyroll from Steam Big Picture (since --kiosk is officially deprecated in chrome).
Feel free to do whatever you want with it :)
