Get started with the Azure App Service integration

Azure App Service is a fully managed platform for building, deploying, and scaling web apps. Aspire apps often run locally during development but require scalable, production-ready hosting environments for staging and production. The Aspire integration allows you to provision or reference an existing Azure App Service environment (App Service Plan) and seamlessly publish your container, executable, and project resources as Azure App Service websites.

In this introduction, you'll see how to install and use the Aspire Azure App Service integration in a simple configuration. If you already have this knowledge, see Azure App Service Hosting integration for full reference details.

Note

To follow this guide, you must have created an Aspire solution to work with. To learn how to do that, see Build your first Aspire app.

Set up hosting integration

To begin, install the Aspire Azure App Service Hosting integration in your Aspire AppHost project:

Install the NuGet package
dotnet add package Aspire.Hosting.Azure.AppService

Next, add an App Service environment to your AppHost project. The environment represents the hosting infrastructure (App Service Plan) where your apps will run:

var builder = DistributedApplication.CreateBuilder(args);
  
var appServiceEnv = builder.AddAzureAppServiceEnvironment("app-service-env");
  
builder.AddProject<Projects.WebApi>("api")
    .PublishAsAzureAppServiceWebsite((infra, website) =>
    {
        // Optional: customize the Azure App Service website here
    });
  
builder.Build().Run();

Caution

When you call AddAzureAppServiceEnvironment, it implicitly calls AddAzureProvisioning—which adds support for generating Azure resources dynamically during app startup. The app must configure the appropriate subscription and location. For more information, see Local provisioning: Configuration.

The preceding code:

  • Creates an Azure App Service environment named app-service-env.
  • Adds a project named api to the AppHost.
  • Configures the project to be published as an Azure App Service website.
  • Provides an optional callback to customize the website configuration.

During local development (when running with ), the project runs locally. When you publish your app, the project is deployed as an Azure App Service website within the provisioned environment.
