Daniel Marbach showa how to combine Async/Await together with the Task Parallel Library to create a message pump for a service bus. Learn how to: * Deal with non-true asynchronous code paths * Avoid unpleasant surprises when you combined Async/Await with the Task Parallel Library * Achieve "graceful" shutdowns by applying cancellation to the asynchronous operations * Achieve throttling with your concurrent operations without blocking unnecessarily If you want to learn how a message pump built can be built with Async/Await and the Task Parallel Library looks like — don't miss this webinar!

5. Recap
Use Task.Run, Factory.StartNew for
CPU-bound work
Use Task directly for IO-bound work
Use async Task insteadof async void
reminder

6. Recap
Librariesand frameworks should use
ConfigureAwait(false)
Async all the way, don’t mix blocking
and asynchronous code
reminder

7. Goals
Combine async/await with the TPL
Throttling your concurrent operations
Graceful shutdowns

16. Recap
Prefer Task.Run over Factory.StartNew
Use CancellationToken to cancel
operations insidetasks
Use SemaphoreSlim to throttle instead
of a custom TaskSchedulerreminder

17. Recap
Don’t use LongRunningor
AttachToParent for Tasks with async
operations
Non-blocking all the way, to maximize
throughputreminder
