Maybe it is a stupid question.

C#

class Program
   {
       static void Main(string[] args)
       {
           Task t = new Task(() =>
           {
               int i = 0;
               for (i = 0; i < 100; i++)
               {
                   Console.WriteLine("*");
               }
           });
           t.Wait();
       }
   }

Why it didn't print?

Solution 1

You wait for the task to be finished, but you never start the task. Use t.Start() to do that:

C#

// code to define task here

t.Start();
t.Wait();

Thanks, it is my fault. It was a typo, the book used Task.Run and I overlooked it.

Not only a typo. I would strongly recommend to write code with your own hands, using your knowledge you get from documentation and theoretical books. Not to copy a code sample and tweak it. Slower way is faster. :-)
