When working with capabilities unique to Data Lake Storage Gen2, such as directory operations and ACLs, use the Data Lake Storage Gen2 APIs, as shown in this article.

 ## Authorize access and connect to data resources
 
 To work with the code examples in this article, you need to create an authorized [DataLakeServiceClient](/dotnet/api/azure.storage.files.datalake.datalakeserviceclient) instance that represents the storage account. You can authorize a `DataLakeServiceClient` object using Microsoft Entra ID, an account access key, or a shared access signature (SAS).
