Razor Pages
Razor Pages is a server-side web application framework built on ASP.NET Core that simplifies page-focused scenarios by combining HTML markup with C# code using Razor syntax. It provides a page-based programming model where each page has a corresponding .cshtml file for the view and a .cshtml.cs file for the page model, handling HTTP requests and business logic. This approach is designed for building dynamic, data-driven web applications with a clean separation of concerns and minimal boilerplate code.
Developers should learn Razor Pages when building traditional server-rendered web applications in ASP.NET Core, especially for scenarios like content management systems, internal business tools, or simple CRUD applications where a page-centric architecture is natural. It is ideal for projects that benefit from the simplicity of the Model-View-ViewModel (MVVM) pattern, as it reduces complexity compared to MVC by eliminating controllers and focusing on individual pages. Use it when rapid development and maintainability are priorities, leveraging built-in features like model binding, validation, and dependency injection.
