How do I make an Autorun.exe file?

Hello, I have been wanting to put my published C# programs on CD's.  I would like for the program to automatically launch the Setup.exe file when the program is inserted in a CD ROM drive on a computer.  How would I make an Autorun.exe file to do this?  Or how would I do this at all?  Also my programs are created using Microsoft Visual Studio C# Express Edition 2005.
