Overview of this book

The ASP.NET Core 2.0 Framework has been designed to meet all the needs of today’s web developers. It provides better control, support for test-driven development, and cleaner code. Moreover, it’s lightweight and allows you to run apps on Windows, OSX and Linux, making it the most popular web framework with modern day developers. This book takes a unique approach to web development, using real-world examples to guide you through problems with ASP.NET Core 2.0 web applications. It covers Visual Studio 2017- and ASP.NET Core 2.0-specifc changes and provides general MVC development recipes. It explores setting up .NET Core, Visual Studio 2017, Node.js modules, and NuGet. Next, it shows you how to work with Inversion of Control data pattern and caching. We explore everyday ASP.NET Core MVC 2.0 patterns and go beyond it into troubleshooting. Finally, we lead you through migrating, hosting, and deploying your code. By the end of the book, you’ll not only have explored every aspect of ASP.NET Core MVC 2.0, you’ll also have a reference you can keep coming back to whenever you need to get the job done.

Using ActionResult


In this recipe, you will learn how to use ActionResult to return with a Web API. ActionResult is a core type of MVC for returning a result from server to client. ActionResult is a base class and its abstract, so we can use one of the derived classes of it, such as JsonResult, ViewResult, RedirectResult, or FileResult.

Getting ready

We will create a Web API controller with the CRUD method to understand what ActionResult we have to return for each HTTP verb.

How to do it...

With ASP.NET Core MVC and Web API-merging, the base class is now the same. ActionResults now returns the HTTP status code result, as the ApiController base class returned before ASP.NET Core.

We will use ActionResults to return the HTTP status code with a CRUD Web API controller:

  1. First, let's create the Web API application by creating an empty web application.
  1. Next, we will add the ASP.NET Core MVC dependency to the project:
"Microsoft.AspNetCore.MVC": "2.0.0",
  1. Next, let's add the following code to Startup.cs...
