Introduction To ASP NET Core Razor Pages

Introduction To ASP NET Core Razor Pages

Currently, an MVC action could return an HTML view, JSON, a file, or anything. Using Pages would force a separation between how you load the page and what services the AJAX callbacks. So, for example, if you were using a Kendo grid and wanted the grid to load via an AJAX call, you would need to use a handler to handle that AJAX call back.

As far as Razor Page vs MVC approaches goes, Razor Pages essentially have no controller. They follow the MVVM (Model-View-View Model) pattern, whereas MVC appropriately razor engine .net core enough follows the MVC (Model-View-Controller) pattern. Essentially, with a Razor Page, the “controller” from MVC is built into the page’s model.

Creating a New ASP.NET Core Project

In this article, I am going to show you how to develop ASP.NET Core Razor Pages Application step-by-step with an example. It is a server-side rendered, page-based model for building web UI with ASP.NET core. In the next sections, we’ll delve deeper into configuring the Razor View Engine to optimize your web application’s performance, functionality, and user experience. In the upcoming sections, I’ll guide you through various aspects of configuring the Razor View Engine in your ASP.NET Core project. We’ll explore everything from foundational tweaks to advanced techniques, empowering you to create web applications that are both functional and delightful to use.

What is Razor engine in ASP.NET Core?

The key difference is that the model and controller code are also included within the Razor Page. It enables two-way data binding and a more straightforward development experience with isolated concerns. It’s vital to realize ASP.NET MVC uses Razor as a template engine, and that they aren’t the same thing. Using the library RazorEngine.NetCore, we can add powerful templating features to any .NET Core application.

Troubleshooting Performance

Any content within the () parenthesis is evaluated and rendered to the output. In the below example, the codes @greeting, @DateTime.Now, and @WeekDay are treated as Implicit Razor expressions. Space is not allowed in the Code expression, as it is used to identify the end of the expression. The Razor View engine evaluates the expressions, and the result is inserted in their place.

A Razor code block can be used to manipulate a model, declare variables, set local properties on a view, etc. However, it would be best if you did not use it for business logic. The Razor view engine is a markup syntax and rendering engine that is used in various Microsoft web development frameworks, including ASP.NET Core MVC. It provides a compact, expressive, and efficient way to generate dynamic HTML content by combining server-side code (typically written in C#) with HTML markup. The Razor view engine has become popular for developers working with ASP.NET Core MVC due to its intuitive syntax and powerful features for creating dynamic web content. It helps developers build maintainable and efficient web applications by promoting the separation of concerns and clean code architecture.

What is View Engine

Any single-page application would use a lot of handlers, or you should point all of those AJAX calls to an MVC controller. While Razor Pages are great for simple pages, there might be better choices for complex scenarios that require intricate routing, multiple views, or complex state management. A Razor Page is very similar to the view component that ASP.NET MVC developers use. As part of the release of .NET Core 2.0, there are also some updates to ASP.NET. Among these is the addition of a new web framework for creating a “page” without the full complexity of ASP.NET MVC. New Razor Pages are a slimmer version of the MVC framework and, in some ways, an evolution of the old “.aspx” WebForms.

  • When search engines index your website, they rely on well-structured HTML and appropriate meta tags to understand its content.
  • As we continue our journey through ASP.NET Core development, remember that the magic lies in the details.
  • Our results are exactly like the previous sample, but now we’re using our Person class to strongly-type our template.
  • The Razor uses the @ symbol to switch from HTML markup to the C# code.
  • By segregating the visual aspect (the view) and the logic (Page Model), Razor Pages promote a clean, maintainable, and testable codebase.
  • Learn how to enhance your ASP.NET Core app by adding a basic controller with efficient dependency injection.
