The DeleteBlobIfExistsAsync(String, DeleteSnapshotsOption, BlobRequestConditions, CancellationToken) operation marks the specified blob or snapshot for deletion, if the blob or snapshot exists. The blob is later deleted during garbage collection which could take several minutes.

Note that in order to delete a blob, you must delete all of its snapshots. You can delete both at the same time using IncludeSnapshots.
