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.

Creating and using controllers with MediatR


In this recipe, you will learn another way to work with MVC controllers without services and repositories.

Note

This recipe could be applied to the WebAPI controller. We could add that it's logical to mix MVC and WebAPI practices in the same controller. Now, there's no difference between them.

Getting ready

We created an empty web application with VS 2017.

How to do it...

  1. First, let's add the MediatR Dependency Injection package in project.json. It will include the MediatR 4.0.0 package:
"MediatR.Extensions.Microsoft.DependencyInjection": "4.0.0"

We will also need the AutoMapper package to map Business models to ViewModels. We will talk about AutoMapper in more detail in Chapter 13, Views, Models, and ViewModels:

"AutoMapper.Extensions.Microsoft.DependencyInjection": "3.2.0"
  1. Next, let's add some configuration in Startup.cs:
public class Startup
{
  public void ConfigureServices(IServiceCollection services)
  {
    var connection = @"Data Source=MyServer;Initial...
