public partial class Form1 : Form
    {
        
        public Form1()
        {
            InitializeComponent();
            Form2 gv = new Form2();
            
            dd();
            this.Hide();
            

            
        }

        private void dd()
        {
            Form2 ss = new Form2();          
            ss.Show();
        }

1. Show the Form1 before the call to Application.Run
2. Keep a timer on Form1 with interval as 3secs and when timer ticks, unload the form.
3. Instantiate Form2 and start message loop on that. Application.Run(new Form2()).

var c = yourMediaPlayer.Ctlcontrols;
c.play();
c.stop();
c.pause();

So which method is better?

A a = new A();

interface1 a = Create()

So is it correct to have 'ModulesPath' of type IList or List?

So here, should 'i' be of type IIAD or of type InstrumentDomain i.e. the concrete class?
