Peter Golde has published a note on his blog about the new MSDN TV video on Power Collections. In the interview, Peter talks about the genesis of the project and various design decisions and he gives an overview of the library structure and the differences between the various collection classes. The whole project is kind of a collaboration between Peter, people at Microsoft who’ve helped launch the whole thing and a community built around Peter’s blog and the PowerCollections forum.
One thing that Peter specifically talks about is the BigList class (see also this post). This is a class with a similar interface to the standard List class, but it’s optimised to work efficiently with large lists, especially for operations like insertions, deletions, copies and concatenations. Peter explains the inner workings of the BigList in detail in the video. Personally, I’ve been using PowerCollections for a while and I think it’s certainly to be recommended as a well thought through collection library. I’ve also had my problems with parts of the design, but nothing insoluble… plus, PowerCollections is not yet final so some problems have to be expected.
Sorry, this blog does not support comments. Why not?
I used various blog hosting services since this blog was established in 2005, but unfortunately they turned out to be unreliable in the long term and comment threads were lost in unavoidable transitions. At this time I don't want to enable third-party services for comments since it has become obvious in recent years that these providers invariably monetize information about their visitors and users.
