C# Q & A


What is Razor Pages in C#?

Razor Pages is a feature in ASP.NET Core, which is a modern and open-source web framework for building web applications in C#. It provides a simple and lightweight way to create web pages with server-side code and is particularly well-suited for building small to medium-sized web applications. Here are some key points about Razor Pages in C#:


  1. Page-Oriented Model: Razor Pages follow a page-oriented model, where each web page is represented by a Razor Page file with a `.cshtml` extension. These pages are typically organized within a folder structure.


  1. Code-Behind: Each Razor Page can have a code-behind file (a `.cshtml.cs` file) that contains the C# code for handling requests, managing data, and defining the page’s behavior. This separation of concerns allows for clean and maintainable code.


  1. Model Binding: Razor Pages support model binding, which means you can easily bind data from HTTP requests (e.g., form submissions) to C# model classes, making it convenient to work with incoming data.


  1. Routing: Routing in Razor Pages is based on conventions, where the URL structure directly maps to the folder and file structure of your pages. This results in clean and SEO-friendly URLs.


  1. View Component: Razor Pages provide a built-in way to create reusable UI components called View Components. These components can be used to encapsulate complex UI logic and rendering.


  1. Integrated with ASP.NET Core: Razor Pages seamlessly integrate with ASP.NET Core, making use of its features like dependency injection, middleware, authentication, and authorization.


  1. Testability: Razor Pages are designed to be testable, allowing you to write unit tests for your page-specific code. You can mock HTTP requests and responses to verify your page’s behavior.


  1. Scaffolding: Visual Studio and other development tools provide scaffolding support for Razor Pages, making it easy to generate boilerplate code for CRUD (Create, Read, Update, Delete) operations and forms.


  1. Razor Syntax: Razor Pages use the Razor syntax for rendering HTML and incorporating C# code within the HTML markup. This syntax is clean, readable, and familiar to C# developers.


  1. Community and Documentation: ASP.NET Core, including Razor Pages, has a strong and active community with extensive documentation and tutorials available, making it accessible to both beginners and experienced developers.


Razor Pages in C# is an excellent choice for building web applications with a focus on simplicity, maintainability, and rapid development. It strikes a balance between the ease of use of traditional web forms and the flexibility of the MVC (Model-View-Controller) pattern, making it a versatile option for a wide range of web projects.
