NHibernate.Bytecode.UnableToLoadProxyFactoryFactoryException - nhibernate

Question

I have the following code set up in my Startup
IDictionary<string, string> properties = new Dictionary<string, string>();
properties.Add("connection.driver_class", "NHibernate.Driver.SqlClientDriver");
properties.Add("dialect", "NHibernate.Dialect.MsSql2005Dialect");
properties.Add("proxyfactory.factory_class", "NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle");
properties.Add("connection.provider", "NHibernate.Connection.DriverConnectionProvider");
properties.Add("connection.connection_string", "Data Source=ZEUS;Initial Catalog=mydb;Persist Security Info=True;User ID=sa;Password=xxxxxxxx");
InPlaceConfigurationSource source = new InPlaceConfigurationSource();
source.Add(typeof(ActiveRecordBase), (IDictionary<string, string>) properties);
Assembly asm = Assembly.Load("Repository");
Castle.ActiveRecord.ActiveRecordStarter.Initialize(asm, source);
I am getting the following error:
failed: NHibernate.Bytecode.UnableToLoadProxyFactoryFactoryException : Unable to load type 'NNHibernate.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.
I have read and read I am referecning the All the assemblies listed and I am at a total loss as what to try next.
Castle.ActiveRecord.dll
Castle.DynamicProxy2.dll
Iesi.Collections.dll
log4net.dll
NHibernate.dll
NHibernate.ByteCode.Castle.dll
Castle.Core.dll.
I am 100% sure the assembly is in the bin. Anyone have any ideas?

Answer 1

This problem occurs when NHibernate.ByteCode.Castle.dll was built with a different target platform as your project. To test this, change your program target platform from one or more of the following:
x64 to x86
x86 to x64
"Any CPU" to x86
"Any CPU" to x64
If any of those solve your problem, then you know that you just need to synchronize the DLL and your target platform.

Answer 2

I had this problem also, my solution was to add in the Assembly that creates session following code.
private NHibernate.ByteCode.Castle.ProxyFactoryFactory requiredButNeverUsed;
