Async looks nice, but this (http://www.jayway.com/2012/10/07/asyncawait-in-c-a-disaster-...) makes me wonder whether it is the right solution for this problem. Breaking what most programmers think are the 'laws' of refactoring is not a good thing.

The problem in the linked article is not async/await, but rather specifically async void, which you don't get by following the straightforward sync->async refactoring rules. A normal void method would start returning Task when turned async (and a non-void method returning T would start returning Task<T>). Async void is a special, distinct beast which is fire-and-forget by definition, and it only exists in async land. Perhaps they should have used a special new keyword for that instead, but in any case, it's a completely orthogonal problem.
