NHibernate and assembly issue

[Pierre]

Hi,

In my C# project (VisitorManagement) I have a subfolder
(BusinessObjects) in which I have put the objects needed for NHibernate
and the mapping files.

In the top of my web service I do a using
VisitorManagement.BusinessObjects; and I'm able to use these objects.
But When I invoke the web service I get the following error.

Code C#:
cfg = new Configuration();
cfg.AddAssembly("VisitorManagement.BusinessObjects ");

Error:
NHibernate.MappingException: Could not add assembly named:
VisitorManagement.BusinessObjects ---> System.IO.FileNotFoundException:
File or assembly name VisitorManagement.BusinessObjects, or one of its
dependencies, was not found.
File name: "VisitorManagement.BusinessObjects"

-----

Code C#:
cfg = new Configuration();
cfg.AddAssembly("VisitorManagement");

Error:
NHibernate.MappingException: persistent class
VisitorManagement.BusinessObjects.TblAuthorisation Level,VisitorManagement.BusinessObjects
not found ---> System.IO.FileNotFoundException: File or assembly name
VisitorManagement.BusinessObjects, or one of its dependencies, was not
found.
File name: "VisitorManagement.BusinessObjects"
It works if I put all the classes in the same folder, but I'd rather
stick to this alternative as it looks way cleaner.

If anybody knows how to sort this problem, I'll be gratefull.

Best reguards,

Pierre
