Unable to load type 'NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle'

Question

Well,

As I read and try every topic similar without success, I decided to post my own question. My solution has a console app and a class library for dataaccess. The Nhibernate configuration is inside the appconfig in the console app (which I'm currently using for debug, as I will after make a Web App and migrate all configuration to web.config).

The exception is well know:

NHibernate.Bytecode.UnableToLoadProxyFactoryFactoryException: Unable to load type NHibernate.ByteCode.Castle.ProxyFactoryFactory,NHibernate.ByteCode.Castle.dll' during configuration of proxy factory class. Possible causes are: - The NHibernate.Bytecode provider assembly was not deployed. - The typeName used to initialize the 'proxyfactory.factory_class' property of the session-factory section is not well formed. Solution: Confirm that your deployment folder contains one of the following assemblies: NHibernate.ByteCode.LinFu.dll NHibernate.ByteCode.Castle.dll ---> System.IO.FileNotFoundException: Could not load file or assembly 'NHibernate.ByteCode.Castle.dll' or one of its dependencies. The system cannot find the file specified.

The steps I took to try to solve it:

1) The dll in the deployment folder - I have the following dll in my bin:
Antlr3.Runtime.dll - v. 3.1.3.42154
Castle.Core.dll - v. 2.5.1.2121
Castle.DynamicProxy2.dll - v. 2.2.0.6628
Iesi.Collections.dll - v.3.0.0.1002
log4net.dll - v. 1.2.10.0
NHibernate.ByteCode.Castle.dll - v.3.0.0.2001 NHibernate.dll - v.3.0.0.1002
Oracle.DataAccess.dll - v.4.112.1.2
Remotion.Data.Linq.dll - v.1.13.41.2

2) The configuration in configuration block

 <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
  <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
  <property name="dialect">NHibernate.Dialect.Oracle10gDialect</property>
  <property name="connection.driver_class">NHibernate.Driver.OracleDataClientDriver</property>
  <property name="connection.connection_string_name">MetaManager</property>
  <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory,NHibernate.ByteCode.Castle</property>
  <mapping assembly="MetaManager.Data"/>
</session-factory>

3) I set my MetaManager.Data project to deploy in a x86 CPU
4) All dll in my bin folder are referenced in the project.

I think this it it. I do not know were else to go :(

I think you have the wrong Castle version. You should be having Castle.Core.dll. NHibernate.ByteCode.Castle.dll probably isn't loaded because it cannot find Castle.Core.dll.

In the download from http://sourceforge.net/projects/nhibernate/files/NHibernate/3.0.0Beta1/, the files located in \Required_For_LazyLoading\Castle are the files you need.
