This tutorial teaches ASP.NET Core MVC web development with controllers and views. If you're new to ASP.NET Core web development, consider the Razor Pages version of this tutorial, which provides an easier starting point.
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:
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.
From the Visual Studio select Create a new project.
Selecct ASP.NET Core Web Application and then select Next.
Name the project MvcMovie and select Create. It's important to name the project MvcMovie so when you copy code, the namespace will match.
Select Web Application(Model-View-Controller), and then select Create.
Visual Studio used the 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 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:
You can debug the app by selecting the IIS Express button
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:
Press Ctrl+F5 to run without the debugger.
Trust the HTTPS development certificate by running the following command:
dotnet dev-certs https --trust
The preceding command displays the following dialog:
Select Yes if you agree to trust the development certificate.
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.
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:
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.
Trust the HTTPS development certificate by running the following command:
dotnet dev-certs https --trust
The preceding command displays the following output:
Trusting the HTTPS development certificate was requested. If the certificate
is not already trusted we will run the following command:
'sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain
<<certificate>>'
This command might prompt you for your password to install the certificate on the
system keychain.
The HTTPS developer certificate was generated successfully.
Enter the admin username and password if prompted. The certificate will now be installed and trusted.
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).
