Create an ASP.NET Core web app in Azure
This article deploys an app to App Service on Windows. To deploy to App Service on Linux, see Create a .NET Core web app in App Service on Linux.
Azure Web Apps provides a highly scalable, self-patching web hosting service. This quickstart shows how to deploy your first ASP.NET Core web app to Azure Web Apps. When you're finished, you'll have a resource group that consists of an App Service plan and an Azure web app with a deployed web application.
If you're looking for how to build and deploy an ASP.NET Framework Web App, that article is available here.
To complete this tutorial:
Install Visual Studio 2017 with the following workloads:
- ASP.NET and web development
If you don't have an Azure subscription, create a free account before you begin.
Create an ASP.NET Core web app
In Visual Studio, create a project by selecting File > New > Project.
In the New Project dialog, select Visual C# > Web > ASP.NET Core Web Application.
Name the application myFirstAzureWebApp, and then select OK.
You can deploy any type of ASP.NET Core web app to Azure. For this quickstart, select the Web Application template, and make sure authentication is set to No Authentication.
Once the ASP.NET Core project is created, the ASP.NET Core welcome page will be displayed, providing numerous links to resources to help you get started.
From the menu, select Debug > Start without Debugging to run the web app locally.
Publish to Azure
In the Solution Explorer, right-click the myFirstAzureWebApp project and select Publish.
Make sure that Microsoft Azure App Service is selected and select Publish.
This opens the Create App Service dialog, which helps you create all the necessary Azure resources to run the ASP.NET Core web app in Azure.
Sign in to Azure
In the Create App Service dialog, select Add an account, and sign in to your Azure subscription. If you're already signed in, select the account containing the desired subscription from the dropdown.
If you're already signed in, don't select Create yet.
Create a resource group
A resource group is a logical container into which Azure resources like web apps, databases, and storage accounts are deployed and managed.
Next to Resource Group, select New.
Name the resource group myResourceGroup and select OK.
Create an App Service plan
An App Service plan specifies the location, size, and features of the web server farm that hosts your app. You can save money when hosting multiple apps by configuring the web apps to share a single App Service plan.
App Service plans define:
- Region (for example: North Europe, East US, or Southeast Asia)
- Instance size (small, medium, or large)
- Scale count (1 to 20 instances)
- SKU (Free, Shared, Basic, Standard, or Premium)
Next to App Service Plan, select New.
In the Configure App Service Plan dialog, use the settings in the table following the screenshot.
|App Service Plan||myAppServicePlan||Name of the App Service plan.|
|Location||West Europe||The datacenter where the web app is hosted.|
|Size||Free||Pricing tier determines hosting features.|
Create and publish the web app
In Web App Name, type a unique app name (valid characters are
-), or accept the automatically generated unique name. The URL of the web app is
<app_name> is your web app name.
Select Create to start creating the Azure resources.
Once the wizard completes, it publishes the ASP.NET Core web app to Azure, and then launches the app in the default browser.
The web app name specified in the create and publish step is used as the URL prefix in the format
Congratulations, your ASP.NET Core web app is running live in Azure App Service.
Update the app and redeploy
From the Solution Explorer, open Pages/Index.cshtml.
<div id="myCarousel" class="carousel slide" data-ride="carousel" data-interval="6000"> HTML tag near the top, and replace the entire element with the following code:
<div class="jumbotron"> <h1>ASP.NET in Azure!</h1> <p class="lead">This is a simple app that we’ve built that demonstrates how to deploy a .NET app to Azure App Service.</p> </div>
To redeploy to Azure, right-click the myFirstAzureWebApp project in Solution Explorer and select Publish.
In the publish page, select Publish.
When publishing completes, Visual Studio launches a browser to the URL of the web app.
Manage the Azure web app
Go to the Azure portal to manage the web app.
From the left menu, select App Services, and then select the name of your Azure web app.
You see your web app's Overview page. Here, you can perform basic management tasks like browse, stop, start, restart, and delete.
The left menu provides different pages for configuring your app.
Clean up resources
In the preceding steps, you created Azure resources in a resource group. If you don't expect to need these resources in the future, you can delete them by deleting the resource group.
From the left menu in the Azure portal, select Resource groups and then select myResourceGroup.
On the resource group page, make sure that the listed resources are the ones you want to delete.
Select Delete, type myResourceGroup in the text box, and then select Delete.
