Application.Run()

Question

Hi friends,

Here I have one question regarding Windows Applications. We all know about Application.Run(new Form1()) in main function.

If I remove Application.Run(new Form1()) and write code like
            Form1 frm = new Form1();
             frm.ShowDialog();

then also mu application gets executed.
So what's the difference?
will you please elaborate on this?

Thanking you
