--- title: Configuration Provider Overview titleSuffix: Azure App Configuration description: Overview of configuration provider libraries of different programming languages. services: azure-app-configuration author: zhiyuanliang-ms ms.author: zhiyuanliang ms.service: azure-app-configuration ms.topic: overview ms.date: 01/22/2025 #Customer intent: I want to learn about the configuration provider libraries of different languages, specifically to track their feature development status. ms.custom: - build-2025 --- # Configuration Provider Overview The Azure App Configuration provider libraries enable developers to configure their applications using centralized configuration located in Azure App Configuration. The API design follows the patterns outlined by the common configuration system in different programming languages to make switching to Azure App Configuration a familiar and easy experience. > [!IMPORTANT] > The configuration provider libraries are higher-level integration libraries that support additional [features](#feature-development-status) in contrast to the Azure SDKs which provide low-level, direct interaction with the Azure App Configuration service. > [!NOTE] > If you use feature flags in Azure App Configuration, we recommend you to use the configuration provider alongside the [feature management](./feature-management-overview.md) libraries, which are designed to work together. ##
