Blocking the thread

.Result, async void and Thread.Sleep in one method. Undo all three.

Beginner20 min on the clock5 graded checks · 100 pointsC# FoundationsPro
Graded by reading your code against the checklist below.

What you build

  • Await the calls rather than blocking on them
  • Return a Task so the caller can await you
  • Accept a CancellationToken and pass it down
  • Wait without holding a thread
  • Let the two independent calls overlap

Done means

Nothing blocks, nothing is fire-and-forget, and the work is cancellable.
