What is the reason for “while(true) { Thread.Sleep }”?

Question

I sometimes encounter code in the following form:

while (true) {
  //do something
  Thread.Sleep(1000);
}

I was wondering if this is considered

I personally don't like Thread.Sleep code. Because it locks the main thread. You can write something like this, if it is a windows application besides it allows you more flexibility and you can call it async:

bool switchControl = true;

while (switchControl) {
  //do something
  await Wait(1);
}

async void Wait(int Seconds)
{
  DateTime Tthen = DateTime.Now;
  do
  {
    Application.DoEvents(); //Or something else or leave empty;
  } while (Tthen.AddSeconds(Seconds) > DateTime.Now);
}
