Create an ASP.NET Framework web app in Azure

Azure Web Apps provides a highly scalable, self-patching web hosting service. This quickstart shows how to deploy your first ASP.NET 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.

Watch the video to see this quickstart in action and then follow the steps yourself to publish your first .NET app on Azure.

If you don't have an Azure subscription, create a free account before you begin.


To complete this tutorial:

  • Install Visual Studio 2017 with the following workloads:

    • ASP.NET and web development
    • Azure development

      ASP.NET and web development and Azure development (under Web & Cloud)

Create an ASP.NET web app

In Visual Studio, create a project by selecting File > New > Project.

In the New Project dialog, select Visual C# > Web > ASP.NET Web Application (.NET Framework).

Name the application myFirstAzureWebApp, and then select OK.

New Project dialog box

You can deploy any type of ASP.NET web app to Azure. For this quickstart, select the MVC template, and make sure authentication is set to No Authentication.

Select OK.

New ASP.NET Project dialog box

From the menu, select Debug > Start without Debugging to run the web app locally.

Run app locally

Publish to Azure

In the Solution Explorer, right-click the myFirstAzureWebApp project and select Publish.

Publish from Solution Explorer

Make sure that Microsoft Azure App Service is selected and select Publish.

Publish from project overview page

This opens the Create App Service dialog, which helps you create all the necessary Azure resources to run the ASP.NET 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.

Sign in to Azure

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.

Create App Service plan

Setting Suggested Value Description
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.

Select OK.

Create and publish the web app

In Web App Name, type a unique app name (valid characters are a-z, 0-9, and -), or accept the automatically generated unique name. The URL of the web app is http://<app_name>, where <app_name> is your web app name.

Select Create to start creating the Azure resources.

Configure web app name

Once the wizard completes, it publishes the ASP.NET web app to Azure, and then launches the app in the default browser.

Published ASP.NET web app in Azure

The web app name specified in the create and publish step is used as the URL prefix in the format http://<app_name>

Congratulations, your ASP.NET web app is running live in Azure App Service.

Update the app and redeploy

From the Solution Explorer, open Views\Home\Index.cshtml.

Find the <div class="jumbotron"> 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>

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.

Portal navigation to 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.
