IntPtr pTarget = [...]; // Find address of target function

var hook = new Hook<MessageBoxWDelegate>(pTarget, MessageBoxWDetour);
hook.Enable();

private int MessageBoxWDetour(IntPtr hwnd, string text, string caption, NativeFunctions.MessageBoxType type)
{
    Console.WriteLine($"Hook triggered: {hwnd:X} {text} {caption} {type}");
