You can find it on our new project site. This build includes the following (straight from the release notes) :

New Platforms

  • NGenerics now has a Silverlight version in this release.  The assemblies have been compiled against Silverlight 3.

New data structures

  • Single-Valued (i.e) not KeyValuePair version of the RedBlackTree.
  • A generic version of the priority queue that can have a key implementing IComparable, or any object with an IComparer instance.

New Patterns

  • Added the Converter pattern under NGenerics.Patterns.Conversion.
  • Added the Specification pattern under NGenerics.Patterns.Specification.

New Extension Methods

  • ConvertTo, Serialize, Deserialize, and DeepCopy extension on Object
  • ForEach extension on IEnumerable<T>
  • IsSimiliar extensions on double
  • Missing list extensions in Silverlight

Changes to existing data structures

  • Added construction mechanism to Singleton - the Singleton value can now be lazy-instantiated.
  • Removed the IVisitable interface and added extension methods for applying a visitor over any instance of IEnumerable<T>. (*breaking change*)
  • Moved visitor-related classes to NGenerics.Patterns.Visitor (*breaking change*)
  • Added FindNode method to GeneralTree.
  • The previous version of the priority queue that accepts integers as keys has been renamed to ClassicPriorityQueue. (* breaking change *)

Bug Fixes

  • Collection Add raised in ObservableHashList instead of Remove on RemoveItem

Misc

  • More documentation.
