In my current project, we have a console app that runs in the background and sends data to a frontend application. The app works great but sometimes it stops working and we need to press a key for it to continue. It turned out it was because of Windows Console's Quick Mode feature. When a user clicks on the console window, it hangs the app execution to allow the user to select the text..
Fortunately, you can easily disable Quick Edit for your app:
// http://msdn.microsoft.com/en-us/library/ms686033(VS.85).aspx
[DllImport("kernel32.dll")]
public static extern bool SetConsoleMode(IntPtr hConsoleHandle, uint dwMode);
private const uint ENABLE_EXTENDED_FLAGS = 0x0080;
private static void DisableQuickEditMode()
{
// Disable QuickEdit Mode
// Quick Edit mode freezes the app to let users select text.
// We don't want that. We want the app to run smoothly in the background.

IntPtr handle = Process.GetCurrentProcess().MainWindowHandle;
SetConsoleMode(handle, ENABLE_EXTENDED_FLAGS);
}
public static void Main(string[] args)
{
DisableQuickEditMode();
// Do stuff
}
