title: Unable to load proxy factory factory exception
body: <p>I am having this annoying error while running my Nhibernate project. It was running okey and all of a sudden it just start asking for a file in this path "d:\CSharp\NH\NH\nhibernate\src\NHibernate\Bytecode\AbstractBytecodeProvider.cs" and when cancel, it throws an exception saying it says
  Unable to load type 'NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle' 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.</p>
  
  <p>Solution:
  Confirm that your deployment folder contains one of the following assemblies:
  NHibernate.ByteCode.LinFu.dll
  NHibernate.ByteCode.Castle.dll</p>
  
  <p>It is become frustrating for me... need help please -:)</p>
