Program.cs

namespace manage_multithreading
{
    class Program
    {
        static void Main(string[] args)
        {
            Task notThatPowerfulTask = Task.Run(() =>
            {
                Console.WriteLine("A long-running task is being executed right now...");
                Thread.Sleep(10000);
            });

            Console.WriteLine("Well, I have only 5s...");
            int result = Task.WaitAny(new[] {notThatPowerfulTask}, 5000);

            if (result == -1)
                Console.WriteLine("I am out... It is taking too much time!");
            
            Console.ReadLine();
        }
