In short, yes.

  The slightly longer story is also yes. But there are some optimizations and tricks. E.g. if the Task is already completed the async method will just continue to the next statement instead of attaching a continuation that will later be called. And in case continuations are used async await will automatically capture the current SynchronizationContext and will assure that the continuation runs on the same.
