NHibernate以前用的是2.0版的，据说新的NHibernate 2.12需要.net 2.0 sp1以上，才能支持。
更改dll后，报如下错误

<property name='proxyfactory.factory_class'>NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>

<property name='proxyfactory.factory_class'>NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
