+This article demonstrates how to use [Microsoft Entra ID managed identities](/azure/app-service/overview-managed-identity) and the [Microsoft.Extensions.AI library](/dotnet/ai/ai-extensions) to authenticate an Azure hosted app to an Azure OpenAI resource.
 
-This article also demonstrates how to use the [Semantic Kernel SDK](/semantic-kernel/overview) to easily implement Microsoft Entra authentication in your .NET application.
-
-By using a managed identity from Microsoft Entra, your App Service application can easily access protected Azure OpenAI resources without having to manually provision or rotate any secrets.
+A managed identity from Microsoft Entra ID allows your app to easily access other Microsoft Entra protected resources such as Azure OpenAI. The identity is managed by the Azure platform and doesn't require you to provision, manage, or rotate any secrets.
 
 ## Prerequisites
 
 * An Azure account that has an active subscription. [Create an account for free](https://azure.microsoft.com/free/?WT.mc_id=A261C142F).
 * [.NET SDK](https://dotnet.microsoft.com/download/visual-studio-sdks)

 * [Create and deploy a .NET application to App Service](/azure/app-service/quickstart-dotnetcore)
 
 ## Add a managed identity to App Service
 
-Your application can be granted two types of identities:
+Managed identities provide an automatically managed identity in Microsoft Entra ID for applications to use when connecting to resources that support Microsoft Entra authentication. Applications can use managed identities to obtain Microsoft Entra tokens without having to manage any credentials. Your application can be assigned two types of identities:
 
 * A **system-assigned identity** is tied to your application and is deleted if your app is deleted. An app can have only one system-assigned identity.
 * A **user-assigned identity** is a standalone Azure resource that can be assigned to your app. An app can have multiple user-assigned identities.

+    dotnet add package Microsoft.Extensions.Azure
+    dotnet add package Microsoft.Extensions.AI
+    dotnet add package Microsoft.Extensions.AI.OpenAI
+    ```
+
+    The preceding packages each handle the following concerns for this scenario:
+

+    - **[Azure.AI.OpenAI](https://www.nuget.org/packages/Azure.AI.OpenAI)**: Enables your app to interface with the Azure OpenAI service
+    - **[Microsoft.Extensions.Azure](https://www.nuget.org/packages/Microsoft.Extensions.Azure)**: Provides helper extensions to register services for dependency injection
+    - **[Microsoft.Extensions.AI](https://www.nuget.org/packages/Microsoft.Extensions.AI)**: Provides AI abstractions for common AI tasks
+    - **[Microsoft.Extensions.AI.OpenAI](https://www.nuget.org/packages/Microsoft.Extensions.AI.OpenAI)**: Enables you to use OpenAI service types as AI abstractions provided by **Microsoft.Extensions.AI**
