Overview of this book

Apps and Services with .NET 7 is for .NET 6 and .NET 7 developers who want to kick their C# and .NET understanding up a gear by learning the practical skills and knowledge they need to build real-world applications and services. It covers specialized libraries that will help you monitor and improve performance, secure your data and applications, and internationalize your code and apps. With chapters that put a variety of technologies into practice, including Web API, OData, gRPC, GraphQL, SignalR, and Azure Functions, this book will give you a broader scope of knowledge than other books that often focus on only a handful of .NET technologies. It covers the latest developments, libraries, and technologies that will help keep you up to date. You’ll also leverage .NET MAUI to develop mobile apps for iOS and Android as well as desktop apps for Windows and macOS.

Defining web user interfaces with Razor views

Let’s see how we can build the user interface of a web page in a modern ASP.NET Core MVC website.

Understanding Razor views

In MVC, the V stands for view. The responsibility of a view is to transform a model into HTML or other formats.

There are multiple view engines that could be used to do this. The default view engine is called Razor, and it uses the @ symbol to indicate server-side code execution.

Let’s review the home page view and how it uses a shared layout:

  1. In the Views/Home folder, open the Index.cshtml file and note the block of C# code wrapped in @{ }. This will execute first and can be used to store data that needs to be passed into a shared layout file, like the title of the web page, as shown in the following code:
