            Console.WriteLine(": "+DateTime.Now.Minute);

Answer 1

You need to prepare your project so it has the necessary resources to call the message box.

Your "Console Application" application does not contain the DLL System.Windows.Forms, therefore, you need to import it into your project.

1. Go to the project menu and click on add reference

2. Choose in this listing by the Assemblies tab the DLL call System.Windows.Forms

3. Add to code the using of this DLL to use the method MessageBox
using System.Windows.Forms;

4. Call the MessageBox with your text
   MessageBox.Show("agora são: " + DateTime.Now.ToString(), "Data/hora atual");

MessageBox.Show(mensagem);
