- C.IReadOnlyDictionary<string, string> department = await blob.GetTagsAsync();

GetPropertiesAsync retrieves the blob's system properties and user-defined metadata without downloading the content. The metadata is available through the returned BlobProperties.Metadata dictionary. Blob index tags are separate from metadata.
