Summary
Building applications that remain responsive whatever task they are executing is something that developers must take care of, especially from the user interface perspective. This chapter explained how to use asynchrony to build responsive applications by first discussing old-style programming models such as the Event-based Asynchronous Pattern and the Asynchronous Programming Model. Both provide techniques to write asynchronous code that runs on separate threads. However, both have some limitations, such as code complexity, issues in returning information to caller threads or functions, and managing errors effectively. Visual Basic 2015 offers the asynchronous pattern based on the Async and Await keywords, which enable you to keep the ...
