Overview of this book

ASP.NET Core MVC helps you build robust web applications using the Model-View-Controller design. This guide will help you in building applications which can be deployed on non-windows platforms such as Linux. In today’s age, it is crucial that you possess the ability to separate the programming and business logic, and this is exactly what ASP.NET Core MVC application will help you achieve. This version comes with a number of improvements that enable fast, TDD-friendly development to create sophisticated applications. You would also learn the fundamentals of Entity framework and on how to use the same in ASP.NET Core web applications. The book presents the fundamentals and philosophies of ASP.NET Core. Starting with an overview of the MVC pattern, we quickly dive into the aspects that you need to know to get started with ASP.NET. You will learn about the core architecture of model, view, and control. Integrating your application with Bootstrap, validating user input, interacting with databases, and deploying your application are some of the things that you will be able to execute with this fast-paced guide.

Most of the web/application layer will be in a server-side language, such as C#, so when you try to optimize the web/application layer, you need to incorporate the best practices of ASP.NET MVC and C#.

A View is what is rendered to the browser, and it can contain presentation logic. Presentation logic represents where and how the data is to be displayed. ViewModels (actually, models specific to the View) are models that hold the data for a particular view.

Neither Views nor ViewModels should contain any business logic as this violates the separation of concerns principle.

Look at the following Razor View code. We are just looping through the list in the model and presenting the data in tabular format—nothing else:
