## Prerequisites

:::moniker range=">= aspnetcore-8.0"
[!INCLUDE[](~/includes/8.0-SDK.md)]
:::moniker-end
:::moniker range=">= aspnetcore-7.0 < aspnetcore-8.0"
[!INCLUDE[](~/includes/7.0-SDK.md)]
:::moniker-end
:::moniker range="<= aspnetcore-6.0"
[!INCLUDE[](~/includes/6.0-SDK.md)]
:::moniker-end

## Create a web app project

Open a command shell, and enter the following command:

```dotnetcli
dotnet new webapp --output aspnetcoreapp --no-https
```

The preceding command creates a new web app project in a directory named `aspnetcoreapp`. The project doesn't use HTTPS.

## Run the app

Run the following commands:

```dotnetcli
cd aspnetcoreapp
dotnet run
```

The `run` command produces output like the following example:

```output
Building...
info: Microsoft.Hosting.Lifetime[14]
      Now listening on: http://localhost:5109
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Development
info: Microsoft.Hosting.Lifetime[0]
      Content root path: C:\aspnetcoreapp
```

Open a browser and go to the URL shown in the output. In this example, the URL is `http://localhost:5109`.

The browser shows the home page.

## Edit a Razor page

Change the home page:

* In the command shell, press Ctrl+C (Cmd+C in macOS) to exit the program.
* Open `Pages/Index.cshtml` in a text editor.
* Replace the line that begins with "Learn about" with the following highlighted markup and code:

  :::code language="cshtml" source="sample/index.cshtml" highlight="9":::

* Save your changes.
* In the command shell run the `dotnet run` command again.
* In the browser, refresh the page and verify the changes are displayed.
