Get started with Razor Pages in ASP.NET Core on macOS with Visual Studio for Mac

By Rick Anderson

This tutorial teaches the basics of building an ASP.NET Core Razor Pages web app. We recommend you review Introduction to Razor Pages before starting this tutorial. Razor Pages is the recommended way to build UI for web applications in ASP.NET Core.

Prerequisites

Visual Studio for Mac

Create a Razor web app

From a terminal, run the following commands:

dotnet new razor -o RazorPagesMovie
cd RazorPagesMovie
dotnet run

The preceding commands use the .NET Core CLI to create and run a Razor Pages project. Open a browser to http://localhost:5000 to view the application.

Home or Index page

The default template creates RazorPagesMovie, Home, About and Contact links and pages. Depending on the size of your browser window, you might need to click the navigation icon to show the links.

Home or Index page

Test the links. The RazorPagesMovie and Home links go to the Index page. The About and Contact links go to the About and Contact pages, respectively.

Project files and folders

The following table lists the files and folders in the project. For this tutorial, the Startup.cs file is the most important to understand. You don't need to review each link provided below. The links are provided as a reference when you need more information on a file or folder in the project.

File or folder Purpose
wwwroot Contains static files. See Static files.
Pages Folder for Razor Pages.
appsettings.json Configuration
Program.cs Hosts the ASP.NET Core app.
Startup.cs Configures services and the request pipeline. See Startup.

The Pages folder

The _Layout.cshtml file contains common HTML elements (scripts and stylesheets) and sets the layout for the application. For example, when you click on RazorPagesMovie, Home, About or Contact, you see the same elements. The common elements include the navigation menu on the top and the header on the bottom of the window. See Layout for more information.

The _ViewStart.cshtml sets the Razor Pages Layout property to use the _Layout.cshtml file. See Layout for more information.

The _ViewImports.cshtml file contains Razor directives that are imported into each Razor Page. See Importing Shared Directives for more information.

The _ValidationScriptsPartial.cshtml file provides a reference to jQuery validation scripts. When we add Create and Edit pages later in the tutorial, the _ValidationScriptsPartial.cshtml file will be used.

The About, Contact and Index pages are basic pages you can use to start an app. The Error page is used to display error information.

Open the project

Press Ctrl+C to shut down the application.

From Visual Studio, select File > Open, and then select the RazorPagesMovie.csproj file.

Launch the app

In Visual Studio, select Run > Start Without Debugging to launch the app. Visual Studio starts Kestrel, launches a browser, and navigates to http://localhost:5000.

In the next tutorial, we add a model to the project.
