async Task vs async void in C#

Question

Hello,

I expected the compiler to show an error and tell me "return Task" from the Show method.

Why don't we need to return a Task? Task is a class and I expected to return an instance of Task class.

What is the difference between static async Task Show() and static async void Show() ?
When should we use each one?

(I am beginner to this topic, could you please write a sample example?)

namespace ConsoleApp2  
{  
    internal class Program  
    {  
        static void Main(string[] args)  
        {  
  
        }  
        static async Task Show() // is it equal with 'static async void Show()' ?  
        {  
             // In fact, **Task is a class and I expected to return an instance of Task class.**  
            Console.WriteLine("!");  
            // we don't return anything!  
        }  
    }  
}
