An invalid or incomplete configuration was used while creating a SessionFactory

Question

and here is the inner exception at the end :

Could not load file or assembly 'ByteCode.Castle' or one of its dependencies. The system cannot find the file specified.

I am adding all references for nhibernate , used all the builds here is my code :

using NHibernate; using FluentNHibernate; using NHibernate.Cfg; using System.Reflection; using FluentNHibernate.Cfg.Db; using FluentNHibernate.Cfg; using NHibernate.ByteCode.Castle; using Castle.Core; using Castle.DynamicProxy;

namespace _3adaseh { public static class NHibernateHelper { private static void ReferByteCode() { //Just to make sure the ByteCodeCastle is loaded ProxyFactory fake = new ProxyFactory(); }

    #region Session
    private static ISessionFactory _sessionFactory;

    private static ISessionFactory SessionFactory

        get

I couldnt test anything so far , I am really getting bored of this error , I added nhibernate references to all my class libraries and nothing is being fixed , can anyone help please??

Answer 1

Make sure that you have assembly references to NHibernate.ByteCode.Castle.dll and Castle.Core.dll (and Castle.DynamicProxy2.dll if you're using NH2.1.2)* to ensure that it is copied into the output directory. Which version of Fluent NHibernate and NHibernate are you using?

* Castle.DynamicProxy2.dll was merged with Castle.Core.dll. The newer merged version of Castle.Core.dll is used in NH3.
