 * Key Vault Secrets, Blob Storage, and Service Bus clients are registered using the <xref:Microsoft.Extensions.Azure.SecretClientBuilderExtensions.AddSecretClient%2A>, <xref:Microsoft.Extensions.Azure.BlobClientBuilderExtensions.AddBlobServiceClient%2A> and <xref:Microsoft.Extensions.Azure.ServiceBusClientBuilderExtensions.AddServiceBusClientWithNamespace%2A>, respectively. The `Uri`- and `string`-typed arguments are passed. To avoid specifying these URLs explicitly, see the [Store configuration separately from code](#store-configuration-separately-from-code) section.
 * <xref:Azure.Identity.DefaultAzureCredential> is used to satisfy the `TokenCredential` argument requirement for each registered client. When one of the clients is created, `DefaultAzureCredential` is used to authenticate.
 * Service Bus subclients are registered for each queue on the service using the subclient and corresponding options types. The queue names for the subclients are retrieved using a separate method outside of the service registration because the `GetQueuesAsync` method must be run asynchronously.
+* An Azure OpenAI client is registered using a custom client factory via the <xref:Microsoft.Extensions.Azure.AzureClientFactoryBuilder.AddClient%2A> method, which provides control over how a client instance is created. Custom client factories are useful in the following cases:
+  * You need to use other dependencies during the client construction.
+  * A registration extension method doesn't exist for the service client you want to register.
