Asynchronous Methods

Explore how to create asynchronous methods in C# using the async modifier and await keyword. Understand how to handle task-based returns, avoid blocking calls, and write cleaner, efficient non-blocking code for responsive applications.

In previous lessons, we used Task.Run and ContinueWith or manual waiting to manage background operations. While powerful, this approach can lead to messy, nested code known as “callback hell”.

To solve this, C# provides two keywords: async and await. These allow you to write asynchronous code that looks and behaves like synchronous code (top-to-bottom execution) while remaining non-blocking.

Creating async methods

An asynchronous method is a method that can suspend its execution without blocking the thread it is running on. ...
