This simplification improves readability by making the asynchronous method look synchronous. Instead, we return nothing (in case of async void and Task method) or an instance of type T (if async Task method). You might have noticed that we never return Task directly. Async methods implicitly create the instance of Task for you, which is used as a return value. However, the way you return the value in asynchronous methods is not applicable here. The article sheds some light on some features and possible pitfalls that you may encounter writing async methods.Īsync method signature can have three types of the return value: void, Task, and Task. Net framework provides you simple and easy to use keywords, which are the async and await modifiers to transform your code from synchronous to asynchronous.Įven though async/await mechanism allows you to do complicated things easier, it is still quite a difficult subject by itself. With asynchronous programming, your logic can be divided into available tasks, which can perform some long-running operations such as downloading a resource from the URL, reading a large file, performing a complex calculation or doing an API call without blocking the execution of your application on UI or service. Asynchronous programming is becoming more and more popular, either in.
