Add README to Aspire.Hosting.Azure.AppService #12105

Copilot · 2025-10-17T00:14:57Z

This PR adds a comprehensive README.md file to the Aspire.Hosting.Azure.AppService package, providing documentation for developers on how to use this package to deploy .NET Aspire applications to Azure App Service.

What's included

The README covers:

Package overview: Brief description of the package's purpose and capabilities
Getting started: Prerequisites and installation instructions
Usage examples:
- Adding an Azure App Service Environment to your AppHost
- Publishing compute resources as Azure App Service websites with customization options
- Configuring the Aspire Dashboard deployment using the WithDashboard extension method
Azure App Service constraints: Documents the limitations when deploying to App Service:
- External endpoints only (requires WithExternalHttpEndpoints())
- HTTP/HTTPS protocols only
- Single target port limitation
Additional documentation: Links to relevant Azure and Aspire documentation
Feedback & contributing: Link to the repository

Pattern consistency

The README follows the conventions used by other Azure hosting packages in the repository, with appropriate adjustments for App Service being a publish-time resource only (no Azure provisioning configuration section included).

All code examples include the required WithExternalHttpEndpoints() call to properly demonstrate the correct usage pattern for Azure App Service deployments, and use the proper WithDashboard extension method for dashboard configuration.

Original prompt

Add a readme to Aspire.Hosting.Azure.AppService

+## Usage example
+
+In the _Program.cs_ file of your AppHost project, add an Azure App Service Environment and publish your project as an Azure App Service website:


website -> WebApp

+    {
+        // Configure the App Service website
+        site.SiteConfig.IsWebSocketsEnabled = true;
+    });
+```


we also need .WithExternalHttpEndpoints() ?

@copilot address this feedback and describe the constraints of app service:

Only external endpoints HTTP or HTTPS based endpoints

Can only have a single endpoint

@copilot implement feedback from @sarsharma

Updated the README to match the conventions used in other Azure hosting packages. Changes include:

Using "In your AppHost project" in the install section
Referencing "AppHost.cs" instead of "Program.cs" in usage examples

These changes align with the patterns established in Aspire.Hosting.Azure.CosmosDB, Aspire.Hosting.Azure.ApplicationInsights, and other Azure hosting packages.

Commit: Will be provided after the changes are pushed.

HTTP/HTTPS protocols only
Single target port limitation

Updated all code examples to include WithExternalHttpEndpoints(). (commit: will be updated after push)

Removed the "Configure Azure Provisioning for local development" section since this is a publish-time resource only. Updated the dashboard configuration example to use the WithDashboard(enable: false) extension method instead of directly setting the property. (commit: will be updated after push)
