Yes, I meant using Task.Run; I was simplifying, as I'd assumed (wrongly) you were familiar with async/await from another language.
Otherwise, from memory, the runtime spec doesn't actually guarantee that await won't run on a threadpool thread - it will under certain circumstances.
And then there are further nuances if there is a synchronisation context and ConfigureAwait(false) is used, as the continuation will be scheduled on a threadpool thread.
