As one of the most important new feature in the C# language, Async is an integral part of the Windows Runtime library. Developers will need to use the async / await features in most, if not all, of their upcoming development efforts. With async methods baked into more and more of the underlying libraries, developers will need strong skills around these features.
In this video training, C# expert and bestselling author Bill Wagner teaches the basics of C# async and await, and the Task Asynchronous Programming Model. Lesson 1 provides the basis for putting async and await into practice in your daily development efforts. All the remaining Lessons are designed to take you through a series of common mistakes developers make using async and await.
In Lesson 2 "Sync over Async", you'll examine where sync over async can creep into an application, and learn how to remove to ensure you don't suffer from its effects. In Lesson 3 you'll explore the perils of async void methods, an issue at the heart of the C# compiler team. In Lesson 4 he'll get you up-to-speed on techniques to ensure that you avoid forcing async methods to run serially. In Lesson 5 you'll learn techniques for unit testing async methods.
