  C# story is a classic example of well-implemented, but leaky abstraction. I would say 99% of the time it works fine and very intuitive. Then 1% of the time something utterly bizarre happens, I've definitely seen very un-intuitive examples when await is used with ContinueWith spawned in an unconventional manner, and the things get hopelessly muddled (you await task t in try-finally but finally only executes after some task that is not part of t completed is something I've seen iirc). I've also seen un-intuitive perf issues with await where replacing it with manual continuations sped things up a lot; again, I think it's very rare, but when it happens it happens. And yeah like the other comment mention, ConfigureAwait 0_o
