[BUG] Cannot delete single Blob Storage snapshot

Library name and version

Azure.Storage.Blobs 12.8.0

Describe the bug

I can create a snapshot, but the SDK only allows me to delete all snapshots for a given blob item, not the one I specified. In general, the SDK usability of blob storage snapshots is very poor.

Expected behavior

Expected to be able to specify deleting a single snapshot

Actual behavior

Can only delete all snapshots

Reproduction Steps

BlobContainerClient blobContainerClient = new BlobContainerClient(/* auth */);
BlobClient blobClient = blobContainerClient.GetBlobClient("foo");
Response<BlobSnapshotInfo> snapshot = blobClient.CreateSnapshot();
blobClient.Delete(DeleteSnapshotsOption.OnlySnapshots); // no overload to specify a single snapshot
blobClient.WithSnapshot(snapshot.Value.Snapshot).Delete(); // returns BadRequest since this operation is only allowed on the base blob, not a snapshot

Environment

Developing .NET Standard 2.1 library project in Visual Studio 2019 on Windows 11, deploying to Azure AppService for Linux

@aaronpburke - it’s possible, though not very obvious with the supplied documentation.

var blobClient = containerClient.GetBlobClient(blobPath);
var snapshotClient = blobClient.WithSnapshot(blobSnapshot);
await snapshotClient.DeleteAsync(cancellationToken);

The key is to get yourself the snapshotClient instead of the blobClient - then just perform the same actions you would as if it were a regular blob.

From the rest api documentation:

Any Blob service operation that is valid for a snapshot can be called by specifying ?snapshot=<DateTime> after the blob name.
