Remarks
Empty value sets, such as new sets returned using this indexer when the key is not found, are not part of the dictionary until items are added to them. When the value set becomes empty again, it is removed from the dictionary. Value sets stay synchronized with their dictionary to always reflect the values associated with their key inside the dictionary.
