        protected override void UpdateInternal(StorageKey key, StorageItem value)
        {
-            innerCache.GetAndChange(key).FromReplica(value);
+            _innerCache.GetAndChange(key)?.FromReplica(value);


This fail before, is this expected?

I think it should be a bug.

I don't understand why SnapshotCache read from store, but write if the snapshot exists...

Because I want to avoid logic changes in this PR, I will throw a different exception, taking a look to the code it seems that it should always exists or it's a failure

src/Neo/Persistence/DataCache.cs

                if (seek_prefix == null)
                {
-                    throw new ArgumentException();
+                    throw new ArgumentException($"{nameof(key_prefix)} with all bytes being 0xff is not supported now");


Why is all 0xff not support? Then SeekDirection should be only Forward and removed from the parameters of this function.

You need 0xff to go Backward for SeekDirection. ApplicationLogs uses this method. However I used IStore interface to do what this can't do. If you can explain whats the problem. I can fix it.

I have a fix, waiting for this PR to merge.
