ASP.NET - Hello World

Create your app

In your command prompt, run the following commands:

dotnet new webApp -o myWebApp --no-https
cd myWebApp

What do these commands mean?

The dotnet new command creates a new application.

• The webApp parameter selects what template to use when creating your app.
• The -o parameter creates a directory named myWebApp where your app is stored.
• The --no-https flag specifies not to enable HTTPS.

The cd myWebApp command puts you into the newly created app directory.

What files were created?

Several files were created in the myWebApp directory, to give you a simple web application that is ready to run.

• Startup.cs contains all the settings and configurations.
• The myWebApp/Pages directory contains some example web pages for the application.
• myWebbApp.csproj defines what libraries are referenced etc.

Run your app

In your command prompt, run the following command:

dotnet run

Once the command completes, browse to http://localhost:5000

Congratulations, you've built and run your first .NET web app!
