I am in the process of creating application project structure and I have some questions. We already decided on the namespace, but still confuse on the actual project structures.

Namespace:
MyCompany.MyApp = Our main app
MyCompany.MyApp.Business = Our Business Objects
MyCompany.MyApp.Main.Windows.Form = Our Form Controls inhereited from MM

Project:
c:\MyCompany\MyApp\MyApp.cproj
c:\MyCompany\MyApp Business\MyApp Business.cproj

c:\MyCompany\MyApp\Windows\Form\Form.cproj
-or-
c:\MyCompany\MyApp\Windows\Windows.cproj
-or-
Something else!

Does the directory and project structure need to match the namespace?
