ASP.NET Core 2.0 MVC & Razor Pages for Beginners 1 Overview I would like to welcome you to ASP.NET Core 2.0 MVC & Razor Pages for Beginners. This book will guide you through creating your very first MVC and Razor Page applications. To get the most from this book, you should have a basic understanding of HTML and be familiar with the C# language. ASP.NET Core is a new framework from Microsoft. It has been designed from the ground up to be fast and flexible and to work across multiple platforms. ASP.NET Core is the framework to use for your future ASP.NET applications. The first application you build will evolve into a basic MVC application, starting with an empty template. You will add the necessary pieces one at a time to get a good under- standing of how things fit together. The focus is on installing and configuring middleware, services, and other frameworks. Styling with CSS is not a priority in this application; you’ll learn more about that in the second application you build. You will install middleware to create a processing pipeline, and then look at the MVC framework. If you already are familiar with MVC or Web API from previous versions of ASP.NET, you will notice some similarities. There still are model classes, which are used as data carriers between the controller and its views. There are, however, many new features that you will learn, such as Tag Helpers and view components. You will also work with Entity Framework to store and retrieve data, implement authentication with ASP.NET Identity framework, install CSS libraries such as Bootstrap, and install JavaScript libraries such as JQuery. Note that dependency injection now is a first-class design pattern. The second solution you will create will contain three projects: one for the database and services (referenced from the other two projects), one MVC project for the user UI, and one Razor Page project for the administrator UI. Pre-existing MVC and Razor Page templates will be used for the two UI projects, and an empty template will be used for the database project. You will modify the database support installed by the templates to instead target the database created by the database project. Only minor modifications will be made to the authentication and routing provided by the templates.

ASP.NET Core 2.0 MVC & Razor Pages for Beginners 2 By the end of this book you will be able to create simple ASP.NET Core 2.0 applications on your own, which can create, edit, delete, and view data in a database. All applications you will build revolve around video data and playing videos. In one application, you will be able to add and edit video titles, and in another, you will build a more sophisticated customer portal, where users can view the course videos that they have access to. Setup In this book, you will be using C#, HTML, and Razor with Visual Studio 2017 version 15.3.5 or later that you have access to. You can even use Visual Studio Community 2017, which you can download for free from www.visualstudio.com/downloads. You can develop ASP.NET Core 2.0 applications on Mac OS X and Linux, but then you are restricted to the ASP.NET Core libraries that don’t depend on .NET Framework, which requires Windows. The applications in this book will be built using ASP.NET 2.0 without .NET Framework. You will install additional libraries using NuGet packages when necessary, throughout the book. The complete code for all applications is available on GitHub with a commit for each task.
