Where can I find the latest version of NHibernate.ByteCode.LinFu.dll that is compiled against NHibernate 3.2?
From 3.2, NHibernate ha its own embedded proxy generator: there are nо more need of NHibernate.ByteCode.LinFu.dll or NHibernate.ByteCode.Castle.dll and I don't think they are supported any more.
I think you have to download the last supported source of NHibernate.ByteCode.LinFu.dll source, and try to compile it against the 3.2.
in NHibernate 3.2 you do not need NHibernate.ByteCode.LinFu.dll because NHibernate 3.2 implements the proxy by itself. so we need modify the config like as:
<property name=”proxyfactory.factory_class”>NHibernate.Bytecode.DefaultProxyFactoryFactory, NHibernate</property>
