await Task.WhenAll() vs Task.WhenAll().Wait()

Question

I have a method that produces an array of tasks (See my previous post about threading) and at the end of this method I have the following options:

await Task         


        

Answer 1

await will return to the caller, and resume method execution when the awaited task completes.

WhenAll will create a task **When All* all the tasks are complete.

WaitAll will block the creation thread (main thread) until all the tasks are complete.
