ASP.NET Core 2 Fundamentals

By: Onur Gumus, Mugilan T. S. Ragupathi

Overview of this book

The book sets the stage with an introduction to web applications and helps you build an understanding of the tried-and-true MVC architecture. You learn all about views, from what is the Razor view engine to tagging helpers. You gain insight into what models are, how to bind them, and how to migrate database using the correct model. As you get comfortable with the world of ASP.NET, you learn about validation and routing. You also learn the advanced concepts, such as designing Rest Buy (a RESTful shopping cart application), creating entities for it, and creating EF context and migrations. By the time you are done reading the book, you will be able to optimally use ASP.NET to develop, unit test, and deploy applications like a pro.

Generating HTML

As discussed in Chapter 1, Setting the Stage, browsers can understand only HTML, CSS, and JavaScript, irrespective of the technology that you use to build the web application. This holds true when building the application in ASP.NET MVC as well.

Most applications get the user input, process the input, and then store the required information in the database to retrieve it later. In the context of web applications, HTML form elements are used to get user input.

The HTML Helpers and Tag Helpers are a couple of ways to generate HTML elements in ASP.NET Core.

HTML helpers are server-side methods that aid in the generation of HTML elements that can be understood by browsers. HTML helpers were the primary method of generating HTML elements up until ASP.NET MVC 5.

Tag Helpers, introduced in ASP.NET Core, also produce HTML elements. Tag Helpers, which we will discuss in a later section of this chapter, look just like HTML elements, where you add attributes to identify them as Tag Helpers...
