Peter and Krys are interviewed on MSDN TV recently about the PowerCollections project… Check it out
Peter does a great job talking about the history and motivation of the project... I do hope that you find value in the way power collections extends System.Collections.Generics.
As Peter says, the major distinguishing philosophy of the project has been to fit in nicely to the existing System.Collections.Generics namespace rather than create a “new world”.
Krys and Peter talk about the new Naming guidelines for generic type parameters… Always good to see more discussion on this one ;-)
To me, one of the most important things about the project is the feedback you give Peter… One the things I want to do is to use this project to vet design ideas with you… so please give him positive and negative feedback.
There is also an interesting discussion on how List<T> works and what it is good for (and not) and how PowerCollection’s BigList<T> fits into this space.
