Ok, I'm pulling my hair out over this, so any help will be hugely appreciated! I'm building a WPF application using the MVVM pattern. In an attempt to get data in at design time I am using the Ninject dependency injection framework in conjunction with a service locator (much like the example in an article at http://jonas.follesoe.no/Yo...
I am working on a WPF application, using the MVVM Pattern. Each ViewModel will need access to a security object, that essentially provides information about the rights the user has.
