namespace intro1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("hola"); //this is the only line added by me
        }
    }
}

Answer 1

Since this is a console application, the "black box" is where the program runs. In the upper left-hand corner of the box is where you should see the word, "hola".

Answer 2

As the program ends immediately after the Console.WriteLine() , the "black box" (the console window) should disappear straight away.

To make it pause so you've got time to see what has been printed, add another line to your program:

Console.ReadKey();

this will cause the app to pause until you press a key.
