Methods

Create(PublicAccessType, IDictionary<String,String>, CancellationToken)

The Create(PublicAccessType, IDictionary<String,String>, CancellationToken) operation creates a new file system under the specified account. If the file system with the same name already exists, the operation fails.

For more information, see Create Container.
