#707 – More Than One Class in A Program Can Contain A Main Method

You typically have one class in your program that contains a function named Main, which acts as the entry point for the application.  The entry point is the first method that will execute when you start your application.

    class Program
    {
        static void Main(string[] args)
        {
            Dog d = new Dog("Kirby", 15);
            d.Bark();
        }
    }

You can actually have more than one class that contains a Main method.  If you do this, however, you must tell the compiler which class contains the Main that it should use as an entry point.  You specify this in the project’s Properties window.

    class ADifferentProgram
    {
        static void Main(string[] args)
        {
            Dog d2 = new Dog("Ruby", 2);
            d2.Bark();
        }
    }
