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";
				string msg = "Unable to load type '" + TypeName + "' during configuration of proxy factory class." + causes;

				return msg;
