Get started with ASP.NET Core MVC

By Rick Anderson

[!INCLUDE consider RP]

This tutorial teaches the basics of building an ASP.NET Core MVC web app.

The app manages a database of movie titles. You learn how to:

[!div class="checklist"]

  • Create a web app.
  • Add and scaffold a model.
  • Work with a database.
  • Add search and validation.

At the end, you have an app that can manage and display movie data.

Create a web app

Visual Studio

From Visual Studio, select File > New > Project.

File > New > Project

Complete the New Project dialog:

  • In the left pane, select .NET Core
  • In the center pane, select ASP.NET Core Web Application (.NET Core)
  • Name the project "MvcMovie" (It's important to name the project "MvcMovie" so when you copy code, the namespace will match.)
  • select OK

Complete the New ASP.NET Core Web Application (.NET Core) - MvcMovie dialog:

  • In the version selector drop-down box select ASP.NET Core 2.2
  • Select Web Application (Model-View-Controller)
  • select OK.

Visual Studio used a default template for the MVC project you just created. You have a working app right now by entering a project name and selecting a few options. This is a basic starter project, and it's a good place to start.

Visual Studio Code

The tutorial assumes familarity with VS Code. See Getting started with VS Code and Visual Studio Code help for more information.

  • Open the integrated terminal.

  • Change directories (cd) to a folder which will contain the project.

  • Run the following command:

    dotnet new mvc -o MvcMovie
code -r MvcMovie

    • A dialog box appears with Required assets to build and debug are missing from 'MvcMovie'. Add them? Select Yes

    • dotnet new mvc -o MvcMovie: creates a new ASP.NET Core MVC project in the MvcMovie folder.

    • code -r MvcMovie: Loads the MvcMovie.csproj project file in Visual Studio Code.

Visual Studio for Mac

  • Select File > New Solution.

    macOS New solution

  • Select .NET Core App > ASP.NET Core > ASP.NET Core Web App (MVC) > Next.

    macOS New project dialog

  • In the Configure your new ASP.NET Core Web API dialog, accept the default Target Framework of *.NET Core 2.2.

  • Name the project MvcMovie, and then select Create.

Run the app

Visual Studio

Select Ctrl-F5 to run the app in non-debug mode.

[!INCLUDE]

  • Visual Studio starts IIS Express and runs the app. Notice that the address bar shows localhost:port# and not something like example.com. That's because localhost is the standard hostname for your local computer. When Visual Studio creates a web project, a random port is used for the web server.

  • Launching the app with Ctrl+F5 (non-debug mode) allows you to make code changes, save the file, refresh the browser, and see the code changes. Many developers prefer to use non-debug mode to quickly launch the app and view changes.

  • You can launch the app in debug or non-debug mode from the Debug menu item:

    Debug menu

  • You can debug the app by selecting the IIS Express button

    IIS Express

Visual Studio Code

Press Ctrl+F5 to run without the debugger.

[!INCLUDE]

Visual Studio Code starts Kestrel, launches a browser, and navigates to https://localhost:5001. The address bar shows localhost:port:5001 and not something like example.com. That's because localhost is the standard hostname for local computer. Localhost only serves web requests from the local computer.

Launching the app with Ctrl+F5 (non-debug mode) allows you to make code changes, save the file, refresh the browser, and see the code changes. Many developers prefer to use non-debug mode to refresh the page and view changes.

Visual Studio for Mac

Select Run > Start Without Debugging to launch the app. Visual Studio for Mac starts Kestrel server, launches a browser, and navigates to http://localhost:port, where port is a randomly chosen port number.

[!INCLUDE]

  • The address bar shows localhost:port# and not something like example.com. That's because localhost is the standard hostname for your local computer. When Visual Studio creates a web project, a random port is used for the web server. When you run the app, you'll see a different port number.
  • You can launch the app in debug or non-debug mode from the Run menu.

  • Select Accept to consent to tracking. This app doesn't track personal information. The template generated code includes assets to help meet General Data Protection Regulation (GDPR).

    The following image shows the app after accepting tracking:

In the next part of this tutorial, you learn about MVC and start writing some code.
