Interesting libraries based on LINQ

Every man and his dog seems to be adding an implementation of LINQ to something.

it's even been ported to javascript http://jslinq.codeplex.com/

But I'm wondering about other more niche LINQ to projects or implementation that are out there that we should k开发者_开发知识库now about.

Linq to Lucene. Lucene is the open source Java Full Text Search (Ported to .Net called Lucene.NET) library and has its own querying syntax. Perfect fit for Linq.

Check out Reactive Extensions, which uses LINQ to define and manipulate asynchronous processing workflows as if they were observable collections.
