Power Collections for .NET is a community project led by Wintellect to develop the best public license collection classes for .NET and is based on .NET Framework 2.0 generics. Browse the Power Collections for .NET documentation or download the latest version. For more information on recent changes in the new drop, check out Peter Golde's blog:

"The big addition in this drop is two new list-like collections. Deque is a double ended queue. This class is like List<T>, but makes adding or removing elements at either end very fast. BigList is the culmination of my thinking about tree-based lists that I talked about earlier. It's a list that is optimized for large (much more than 100 items) lists, and allows efficient insertion, deletion, concatination, and copying."
