Distinguishing between UI command & domain commands
I am building a WPF client application using the MVVM pattern that provides an interface on top of an existing set of business logic residing in a library which is shared with other applications. The business library followed a domain-driven architecture using CQRS to separate the read and write models (no event sourcing). The combination of technologies and patterns has brought up an interesting conundrum:

Several times, I’ve found myself in a situation where I want to add functionality to an existing Observer–Observable relationship.
