Continuation not running C#

Question

Consider the following code

class Program
{

    static void Continue()
    {
        Console.Out.WriteLine("Continue t1"); 
    }

    static async Task AsyncStart()
    {
        Console.Out.WriteLine("AsyncStart"); 
        return;
    }

    static void Main(string[] args)
    {

        Task t3 = AsyncStart().ContinueWith((ant) => { Continue(); });

        Console.Out.WriteLine("BEFORE"); 
        Task.WhenAny(new Task[] { t3 });
        Console.Out.WriteLine("AFTER");
     }
 }

The output is

AsyncStart
BEFORE
AFTER
Press any key to continue . . .

Continuation is not running!!!!

Yes, I understand the AsyncStart does not contain any await (CS1998), but I still expect t3 to run the continuation. I am missing something very basic

Answer 1

Your process ended before the continuation (which runs on a background thread) had the chance to run.
