The project used in this case study is a collection of MVVM style base classes, reflection code, and various utility functions.

Why Do We Need Architectural Diagrams?

Software architecture diagrams, when created well, and sparingly, can greatly improve communication within the development team and with external stakeholders. They require an understanding of the intended audience, and thoughtful restraint on what to include. Resist the temptation to think that diagrams are unnecessary or unhelpful, simply because there have been plenty of cases of bad diagrams.
