LinFu proxy doesn't work with NHibernate 2.1.0.Alpha1 while Castle does

Hi,

I've updated one of our projects to 2.1.0.Alpha1 and adjusted the
NHibernate configuration to use LinFu:

1. Adjusted the configuration file

<property name="proxyfactory.factory_class">

NHibernate.ByteCode.LinFu.ProxyFactoryFactory,
NHibernate.ByteCode.LinFu

</property>

2. Added dependancies to the bin folder

Added files :
* LinFu.DynamicProxy.dll
* NHibernate.ByteCode.LinFu.dll


Now when I execute the unittest project I get the following error:


===================================
Unable to load type 'NHibernate.ByteCode.LinFu.ProxyFactoryFactory,
NHibernate.ByteCode.LinFu' 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.FileLoadException : Could not load file or assembly
'NHibernate, Version=2.1.0.1001, Culture=neutral, PublicKeyToken=null'
or one of its dependencies. The located assembly's manifest definition
does not match the assembly reference. (Exception from HRESULT:
0x80131040)
===================================

I've checked the output folder and all required files are there:
* Iesi.Collections.dll
* LinFu.DynamicProxy.dll
* log4net.dll
* NHibernate.ByteCode.LinFu.dll
* NHibernate.dll

So then I started Sysinternals Proces Monitor and these are the LinFu
related errors that got logged:

1:09:34.8874798 PM ProcessInvocation.exe 3288 QueryAllInformationFile
C:\****\bin\NHIBERNATE.BYTECODE.LINFU.DLL BUFFER OVERFLOW

Some sort of BUFFER OVERFLOW error on the LinFu assembly.

So now I'm pretty much lost as it seems that I did all stuff required
to make it work but is does not while the Castle framework works
without any problems.


Ideas anyone?

Hi Ramon,

That is strange. At this point, I can't tell if it's caused by
NHibernate's LinFu Bytecode Provider or LinFu itself. Do you have the
sample code that causes the error, and can this error reproduced just
by using LinFu.DynamicProxy.dll on its own?
