A ConcurrentHashSet implementation based on .NET's ConcurrentDictionary

This implementation supports basic operations per item without HashSet's set operations as they make less sense in concurrent scenarios IMO:

var concurrentHashSet =
    new ConcurrentHashSet<string>(

if (concurrentHashSet.Contains("BAR"))
