Important

Microsoft Graph SDKs use the v1.0 version of the API by default, and do not support all the types, properties, and APIs available in the beta version. For details about accessing the beta API with the SDK, see Use the Microsoft Graph SDKs with the beta API.

For details about how to add the SDK to your project and create an authProvider instance, see the SDK documentation.
