# Tutorial: Get started with ASP.NET Core
|
|
|
|
This tutorial shows how to use the .NET Core command-line interface to create an ASP.NET Core web app. You'll learn how to:
|
|
|
|
> [!div class="checklist"]
|
|
> * Create a web app project.
|
|
> * Enable local HTTPS.
|
|
> * Run the app.
|
|
> * Edit a Razor page.
|
|
|
|
At the end, you'll have a working web app running on your local machine.
|
|
|
|
|
|
|
|
|
|
## Prerequisites
|
|
|
|
* Install the [!INCLUDE [](~/includes/2.1-SDK.md)].
|
|
|
|
## Create a web app project
|
|
|
|
* Open a command shell, and enter the following command:
|
|
|
|
```console
|
|
dotnet new webapp -o aspnetcoreapp
|
|
```
|
|
|
|
## Enable local HTTPS
|
|
|
|
* Trust the HTTPS development certificate:
|
|
|
|
# [Windows](#tab/windows)
|
|
|
|
```console
|
|
dotnet dev-certs https --trust
|
|
```
|
|
|
|
The preceding command displays the following dialog:
|
|
|
|
|
|
|
|
Select **Yes** if you agree to trust the development certificate.
|
|
|
|
# [macOS](#tab/macos)
|
|
|
|
```console
|
|
dotnet dev-certs https --trust
|
|
```
|
|
|
|
The preceding command displays the following message:
|
|
|
|
*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.
|
|
|
|
Password:*
|
|
|
|
Enter your password if you agree to trust the development certificate.
|
|
|
|
# [Linux](#tab/linux)
|
|
|
|
See the documentation for your Linux distribution on how to trust the HTTPS development certificate.

|
|
|
|
* Open *Pages/About.cshtml* and modify the page with the following highlighted markup:
|
|
|
|
[!code-cshtml[](sample/getting-started/about.cshtml?highlight=9)]
|
