My older dll was file and assembly version 0.1.0.0.
I setup NHibernate with this code:
Configuration cfg = new Configuration().Configure();
foreach (Assembly assembly in assemblies)
{
cfg.AddMappingsFromAssembly(assembly);
}
SessionFactory = cfg.BuildSessionFactory();
Storage = storage;
return cfg;
And the full error message is pasted below:
Server Error in '/' Application.
