/NHibernate.Search

compile it yourself from the newest sources, with referenced libraries updated

The goal of this project is to get NHibernate.Search compiled against .Net4 and newest dependencies

BTW, you get .Net4-compatible NHibernate for free.

I've gathered sources of most of the NHibernate.Search's dependencies and provided a common VS2010 solution to compile them all.

WARNING: 
Sources contain my patches to make them work together and compile on .Net4.
I'm working on getting these patches into main dev branches of the respective projects.

Hibernate changes:
Iesi.collections: .Net4's System.Collections.Generic compatibility
HQL handling: Parsers regenerated with newer version of antlr3
