An Introduction To ASP NET Razor Pages

RoutingAs compared to MVC routing, Razor Page routing is very simple. All the pages inside Pages folder will call by file name after domain name. HandlersWe use handlers to perform server side operations like getting the data, posting the data. These handlers are something like Http Verb we used in MVC like Get(), Post() etc. Model Auto-UpdatingDefined model with Razor page will update automatically on Code-Behind file. You don’t need to take care to bind your model with specific operation.

ASP.NET Core 2.0 has introduced several new features and a new project template is among these new features. Microsoft has introduced some new project templates which help us to create new types of applications, except for MVC and Web API. Now, we can create Razor Page applications and SPA applications using Angular or React. Today, we will talk about more about Razor pages – what actually a Razor page is, how to create Razor page applications, and some of the fundamentals of Razor pages. From this tutorial, it is clear that razor pages is the default and easy-to-use framework for building server-side, dynamic, and data-driven web pages with a clear separation of concerns. We need to change the welcome message to add the following code to cs.cshtml.cs file and accessing it in the index.cshtml file with the @Model.Message property.

Search code, repositories, users, issues, pull requests…

Then, provide the name of the application and location to save it and click OK. To create a Razor Page application, you should have Visual Studio 2017 with version 15.3 or above with .NET Core SDK 2.0 installed on your system. You can download .NET Core SDK 2.0 from Here and update your Visual Studio using “Visual Studio Installer”. Finally, I use the Material Icon Theme extension, which provides icons for files and folders in the Explorer pane. _ValidationScriptsPartial is in the solution explorer in the shared folder. For the second and third files above to be effective, and since they are already loaded in the partial view file, they need to be rendered in the Edit file using the jQuery code below.

To access the Products Razor Page, we just created above, type /Products in your browser URL just after your site’s main URL and you will see the following page rendered in the browser. Razor Pages are physical .cshtml files and to create Razor Page you need to create a Pages folder inside your project. This is by convention but if you want to create a folder with asp net razor tutorial some other name then you have to tell ASP.NET where the Razor Pages are located. If you are using Visual Studio 2019, then you simply need to right-click on the Pages folder inside your solution explorer and choose Razor Pages… option from the context menu. The cookie consent banner across the top of the page forms part of ASP.NET Core templates since version 2.1.

Root files

Once you have created the application, the dotnet restore command is automatically executed. This results in dependencies and tools required by the project being restored. If this is your first .NET Core application, this command can take a little while to complete. Once completed, you can open the Bakery folder from within VS Code to see the files and folders that were created. Under the hood, Razor Pages use the same routing infrastructure that is used by MVC but there are few differences related to configuration.

At this point, you have used the .NET Core SDK and Visual Studio Code to create a new Razor Pages application. You have reviewed the contents of the project folder, and you have launched the application in a browser. In the next section, you will add a new page and begin customising the site content. You can manually create the folder, and then open it in VS Code, or you can open VS Code and use its integrated terminal to create a directory with the standard mkdir command. The terminal in VS Code is accessed by pressing Ctrl+’ (or ⌘+’ on a Mac).

Decorator Design Pattern in ASP.NET Core 5

It doesn’t mean that you need to dump MVC totally and migrate your complete application to Razor Pages. Razor Pages are good for simple page-centric scenarios only and you still have to stick to the MVC pattern if you are building complex pages with a lot of functionality. Razor Pages are self-contained files similar to PHP files, XAML controls, or ASP.NET Web Forms and as compared to MVC, they follow a different approach of building web pages using ASP.NET Core. They allow developers to mix HTML and server-side C# directly within a single file without the need of creating Controllers, View Models, etc. These pages can coexist with traditional MVC and Web API controllers within the same project and can be used for scenarios where you need to build simple pages without too much logic in them. Ideal candidates can be About Us, Contact Us, and Site Map pages.

These actions are also highly coupled in the sense that most of the time they require similar initialization logic, same View Model, and even the same Razor View. You have two options now to create web applications in ASP.NET Core so the decision whether to use MVC or Razor Pages should be made upfront because there are many differences between them. If you’re creating a new app using Razor, I strongly suggest considering Razor Pages as the default approach. In this tutorial, I tried to give you an in-depth overview of Razor Pages.
