Hastables are deprecated now because with .NET 2.0 and above the Dictionary class is introduced which is much more efficient because it does not need to box or unbox data while adding/retrieiving items.

ListDictionary should be used when the number of items are small (usually less than 10). Else if you are sure that your list will have more items, than use Dictionary.

If you are not sure about the number of items, then use a HybridDictionary.
