Error: Many entry point, why?

Hi everyone, please help me with this: I have a class named classA. classA has a main function: class classA { public static void Main() { ........ } } I have another class, classB, inherit classA. classB also has a main function classB: class classB:classA { public new static void Main() { ...... } } I already use the word "new" for classB (public new static void Main() ), but the compiler (VS 2003)still says "Error: More than one entry point" . So's what's wrong with my code? Thanks.
