Coding an asynchronous API comes with its own set of challenges. In Pluralsight's Building an Async API with ASP.NET Core video course taught by Kevin Dockx, you'll gain the ability to increase the scalability and performance of your API by writing async code.
In this course, you will first learn how asynchronous code actually works and what benefits it can have. In the following, you will learn how to use the EF Core data store asynchronously, how to display data through the API, and how to call a service asynchronously. Finally, you'll explore how to avoid common mistakes when writing async code. When you finish this course, you'll have the asynchronous code skills and knowledge needed to build a fully async API with ASP.NET Core.
