What’s the difference between Task.Start/Wait and Async/Await?

I may be missing something but what is the difference between doing: public void MyMethod() { Task t = Task.Factory.StartNew(DoSomethingThatTakesTime); t.Wait(); UpdateLabelToSayItsComplete(); } public async void MyMethod() { var result = Task.Factory.StartNew(DoSomethingThatTakesTime); await result; UpdateLabelToSayItsComplete(); } private void DoSomethingThatTakesTime() { Thread.Sleep(10000); } 6 Answers 6
