I'm a fan of async/await in C#, but never use them. I've been deep into the bowels of callback hell and it's lame. Debugging other people's asynchronous state wrangling machines is also lame. But I just don't write enough asynchronous code to actually benefit that much from async/await, and not all asynchronous patterns map nicely to the hierarchical nature of call graphs for me to take advantage of async/await all that sanely, as I found out from a few attempts to force the issue. And how do I add good debug visualizers to display tasks in flight? How do I serialize out long running async tasks? How do I modify things without breaking that serialization?
