Components within the underlying MVC framework still have their uses such as using controllers for building RESTful APIs. You can still choose to use ASP.NET Core MVC to build your ASP.NET Core web applications. If you are porting an existing .NET Framework MVC application (MVC5 or earlier) to .NET Core, it may well be quicker or easier to keep with the MVC framework.
Razor Programming Languages
- Some of the best ways to contribute are to try things out, file issues, join in design conversations,and make pull requests.
- Developers just starting their ASP.NET web development journey might have heard the term Razor, and had developers apply it within many different situations.
- Razor is a markup syntax that flows seamlessly between Hypertext Markup Language (HTML) and C# and Visual Basic syntax, with C# being the most commonly used.

- Or you can build your own if you have an interest in, and an aptitude for programming.
When looking at an ASP.NET solution, Razor files will have extensions of .cshtml, .vbhtml, or .razor. The compiled artifact of Razor is executable code that writes HTML to the HTTP response. Razor Pages makes use of the popular C# programming language for server-side programming, and the easy-to-learn Razor templating syntax for embedding C# in HTML mark-up to generate content for browsers dynamically. Again, while Razor is reuseable by the OSS community, each framework’s particulars are tied to the inner-workings of ASP.NET Core. In short, OSS authors might need to rebuild elements to bring a similar API surface to developers. From our Blazor components, we can execute both client-side interactive code and make asynchronous server calls to run server-side dependencies.
Or you can build your own if you have an interest in, and an aptitude for programming. The low-level building blocks of Blazor are components, which are self-contained and reusable elements that we can compose within a page. ASP.NET Core MVC will resolve views based on the registered view engines and their internal conventions. All developers need to understand the view locating rules, which I’ve written about in a previous blog post, which I highly recommend reading. This site is dedicated to helping developers who want to use the ASP.NET Razor Pages web development framework to build web applications. In this small Razor sample, we can see uses of code blocks, setting an MVC-specific property of ViewData with an indexed value, and inline access of the same value.
What about the MVC Framework?
However, Razor Pages removes a lot of the unnecessary ceremony that comes with the ASP.NET implementation of MVC and is a simpler, and therefore more maintainable development experience. If you want a dynamic web site, that is one where the content is regularly being added to, you have a number of options available to you. You can use a Content Management System (CMS), of which there are many to choose from including WordPress, Umbraco, Joomla!

Except for some additional razor keywords like @code, Razor syntax in Blazor should be familiar to developers. Underscoring the philosophy of Blazor, writing client-side rich experiences should be intuitive for developers coming from MVC or Razor Pages applications. Blazor is another technology within the ASP.NET Core family that relies on Razor syntax. Blazor is a framework for building interactive client-side experiences powered by Razor, SignalR, and minimal JavaScript.
We can see the @page directive again, similar to the usage under the Razor Pages programming model. The directive makes the Razor page accessible via a route, in this case, the current site’s root path. Also check out the .NET Homepage for released versions of .NET, getting started guides, and learning resources. Both core team members and external contributors send pull requests which go through the same review process. Some of the best ways to contribute are to try things out, file issues, join in design conversations,and make pull requests.
ASP.NET helpers are components that can be accessed by single lines of Razor code. The key difference between Razor Pages implementation of the MVC pattern and ASP.NET Core MVC is that Razor Pages uses the Page Controller pattern instead of the Front Controller pattern. Razor Pages is included within .NET Core from version 2.0 onwards, which is available as a free download as either an SDK (Software Development Kit) or a Runtime. The SDK includes the runtime and command line tools for creating .NET Core applications. The SDK is installed for you when you install Visual Studio 2017 Update 3 or later.
If you are a seasoned developer, the Razor Pages framework is likely to add to your skillset with the minimum amount of effort. Razor Pages is suitable for all kinds of developers from beginners to enterprise level. It is also relatively easy for the beginner to learn, and it includes all of the advanced features of ASP.NET Core (such as dependency injection) making it just as suitable for large, scalable, team-based projects. The goal of Razor syntax is to produce server-side rendered HTML artifacts for web clients.

The driving philosophy behind Razor is to bring ASP.NET developers closer into the web ecosystem by leveraging existing syntax and technologies. The traditional aspx format put ASP.NET developers at a disadvantage and made it difficult to leverage the HTML community’s advancements. The closer ASP.NET developers are to HTML, the more they can lean on other professionals, ecosystems, and technologies to deliver web-based solutions. Rather than be an opaque abstraction, Razor embraces HTML, CSS, and JavaScript as a necessity when building web applications.
In general, code modifying HTML elements will run on the client, while code that accesses server dependencies will razor developers run on the server, with the results being marshaled back to the client via SignalR. Razor Pages is a great starting point for folks starting their ASP.NET journey, as it distills the required parts needed to build an interactive web experience. Adopters of Razor Pages will interact with concepts like rendering HTML, model binding, and request/response handling. As mentioned in the previous section, Razor’s intended use case was for the ASP.NET MVC framework, primarily powering the View parts that developers would be building. While ASP.NET MVC can support different view engines, the default is the RazorViewEngine found under the Microsoft.AspNetCore.Mvc.Razor namespace.
