I am getting the following error after upgrading from NHibernate 1.2.0.GA to NHibernate-2.1.2.GA:

In my Project, I have added lgo4net, NHibernate, and NHibernate.ByteCode.Castle as a reference. Copy Local is set to True for all of those. I even added "using NHibernate.ByteCode.Castle" to the class file that is calling NHibernate functions as well. Any ideas? Where is it looking for this DLL?

To clarify, I have a client that calls a Framework project (which actually makes the NHibernate calls). The Framework project is what I refer to when I say I have added log4net, NHibernate, and NHibernate.Bytecode.Castle as a reference.

To throw another wrench in this, if I add NHibernate.Bytecode.Castle to my client, it works. But it shouldn't have to work that way...we don't want any client using the Framework to have to add this reference.

If you are having an issues with the assembly not copying local, I had this same issue and used the following solution.

Add a class to the framework project that makes code references into the assemblies missing. I could not find the reason Visual Studio would not copy the dll's local even with "Copy Local" set true, but making code references into the missing assemblies did trigger the copy local.
