Question on proper location of class in WCF App

B

Bill Gower

#1
I have a class called LWUser which contains the properties and methods that
represent a user of the system. This class sits in the Business Services
solutions on the server. I also have a class called LWUserUI which sits on
the client side in the Client solution. I am going to create a third class,
LoggedInUser, a singleton class, which holds information such as security
access, user info for the current logged in user. I am going to use a
singleton class as there can only be one user logged in and I need this
information throughout the app. Where should the class, LoggedInUser sit,
in the the UI solution on the client side or in the Business Services
solution on the server side?

Where does the concept of "logged-in" sit? Is it an aspect of the LWUser
class or of the LWUserUI class? The LoggedInUser class should sit nearest
where it gets its data from.

On the other hand, if "LoggedInUser" is a unique concept that isn't
dependant on either the businesss services layer or on the UI, then perhaps
it should be its own service.
