Namespaces work a bit differently in VB .NET than C#. In VB .NET, the namespace you specify at the project level is a "root namespace". This means that any namespace you specify in a class definition gets appended as a suffix to this namespace.

For example, if you have WS.SAFISNET.Business as your project's root namespace, and you have the following namespace in your business object source code:

Namespace WS.SAFISNET.Main.Business

Then the full name of your business object is:

WS.SAFISNET.Main.Business.WS.SAFISNET.Main.Business

Which I'm sure isn't what you want! Removing the namespace from the source code as you did, gave the business object the correct name:

WS.SAFISNET.Main.Business
