![]() Your application stops responding, and you might conclude that it has failed when instead it's just waiting. If any process is blocked in a synchronous application, all are blocked. Application areaĪsynchrony proves especially valuable for applications that access the UI thread because all UI-related activity usually shares one thread. NET and the Windows Runtime contain methods that support async programming. The following table shows typical areas where asynchronous programming improves responsiveness. In an asynchronous process, the application can continue with other work that doesn't depend on the web resource until the potentially blocking task finishes. If such an activity is blocked in a synchronous process, the entire application must wait. Access to a web resource sometimes is slow or delayed. ![]() Async improves responsivenessĪsynchrony is essential for activities that are potentially blocking, such as web access. This topic provides an overview of when and how to use async programming and includes links to support topics that contain details and examples. ![]() As a result, you get all the advantages of asynchronous programming with a fraction of the effort. The compiler does the difficult work that the developer used to do, and your application retains a logical structure that resembles synchronous code. However, traditional techniques for writing asynchronous applications can be complicated, making them difficult to write, debug, and maintain.Ĭ# supports simplified approach, async programming, that leverages asynchronous support in the. You can avoid performance bottlenecks and enhance the overall responsiveness of your application by using asynchronous programming.
