Call Task from Thread

Question

Which task is called this example?

new Thread(() => { 
Console.WriteLine("AAA"); 
Task.Delay(5000); 
Console.WriteLine("BBB"); }).Start() ;

When we call thread's sleep, we call current thread and what's up with task.Delay if we do not create new task as my example?

In this example I call Task.Delay() without create Task.

Answer 1

Task.Delay doesn't delay the "current task", it creates a new task that completes after the specified delay. It also doesn't block and will return immediately, unlike Thread.Sleep .

Using Task.Delay without await , ContinueWith or other similar methods that either wait for the completion or schedule a continuation is not useful at all.
