NHive is intended to become a new .NET Collection Library, using the C5 Collections library (version 1.0.1) as a starting point and released under a more liberal licence than the original PowerCollections collections library license. For support of STL-like algorithms, integration with results of the CSTL project are considered (after the start of the NHive project the Power Collections have moved to CodePlex and are now distributed under a much more liberal license).

The project is currently in a prototyping phase and is not likely to release anything soon. However, C5 Collection users and/or evaluators that are looking for C5 dictionary implementations that support the standard System.Collections.Generic.IDictionary interface, should have a look in the Subversion repository (http://nhive.googlecode.com/svn/projects/c5/tags/C5-2.0.0-alpha1/).
