Configure Azure Storage Shared Key Authentication

See more REST Examples

Demonstrates Rest.SetAuthAzureStorage, which associates an AuthAzureStorage provider so Chilkat automatically adds a Shared Key Authorization header. The provider supplies the account name, base64 account key, service, and scheme.
