- Asynchronous programming has traditionally been really, really hard
- Keeps UI from being blocked on long running tasks
- Lots of newer APIs are async
- Mobile OSes disallow networking to run on UI thread

Let's look at some code
Async greatly simplifies exception handling
- Not asyncing all the things!
- Avoid "async void". At almost all costs.
