 Preview APIs are periodically deprecated. If you're using a preview API version, update your application to target the GA API version. To migrate from a preview API version to the `2024-11-30 (GA)` API version using the SDK, update to the [current version of the language specific SDK](sdk-overview-v4-0.md).
