This sample demonstrates how to interact with the Azure Data Lake Storage Gen1 service using the .NET SDK. The sample walks through following main steps: - Acquire an Azure ActiveDirectory OAuth token (ServiceClientCredential) - Create a Data Lake Storage Gen1 client object using the account path and OAuth token instance. - Use the methods on the client object to interact with the store. - Get a write stream and write a file on store. - Get a read stream and read the file from store. - Rename file. - Enumerate directories and delete directories recursively.
