A simple program showing Task.Delay(1) and what really happens

DelayTest.cs

async Task Main()
{
	for (var i = 0; i < 20; i++)
	{
		await Run(); // Just to show it many times
	}
}

public async Task Run()
{
	var sw = Stopwatch.StartNew();
	await Task.Delay(1);
	sw.Stop();
  Console.WriteLine(sw.ElapsedMilliseconds);
}
