Razor views in ASP.NET MVC are a view engine that allows you to create the user interface (UI) or presentation layer of your web application. Razor views are designed to be concise and expressive, making it easy to combine HTML markup with server-side code for dynamic content rendering. Razor views work by dynamically generating HTML content on the server and sending it to the client's web browser.

Here's an overview of how Razor views work and their key features:

1. Concise Syntax:

• Razor uses a concise syntax for embedding server-side code within HTML markup. Code is enclosed in @{ ... } blocks, making it easy to switch between markup and code.

2. HTML Integration:

• You can seamlessly integrate HTML markup with C# or VB.NET code. This allows you to generate dynamic content, including data from models, conditionals, loops, and more, directly within your views.

3. Code Execution on the Server:

• Razor views are executed on the server, not the client. When a user requests a page, the server processes the Razor view, executes any server-side code, and generates HTML content as the response.

4. Layouts and Views:

• Razor views support layouts, which enable you to define a common structure (such as headers, footers, and sidebars) for your views. You can create reusable layouts that wrap individual views, providing a consistent look and feel across your application.

5. Model Binding:

• Razor views can bind to models or view models, allowing you to pass data from your controllers to your views. You can access model properties directly within your views, making it easy to display data and respond to user input.

6. Helpers and Tag Helpers:

• Razor views provide built-in HTML helpers and tag helpers to simplify common tasks like rendering form elements, generating URLs, and working with forms.

7. Intellisense Support:

• IDEs like Visual Studio provide IntelliSense support for Razor views, helping you write code more efficiently and catch syntax errors.

8. Extensibility:

• You can create custom HTML helpers and Razor extensions to encapsulate complex UI components or frequently used code patterns, promoting code reuse.

9. View Compilation:

• Razor views are compiled into .NET assemblies, which improves performance and allows for early detection of syntax errors.

10. Separation of Concerns: - Razor views encourage the separation of concerns by keeping presentation logic separate from application logic. Controllers handle business logic, models manage data, and views handle rendering.

Overall, Razor views in ASP.NET MVC are a powerful tool for creating dynamic and data-driven web pages. They enable you to build interactive and responsive web applications by combining HTML markup with server-side code, promoting clean code organization and separation of concerns.
