Summary

We've now investigated the benefit of having an application framework and started constructing our own. We've discovered a variety of different ways to encapsulate our required functionality into our framework and know which situations to use each in. After exploring a number of manager classes, we have also begun to expose functionality from external sources, but without being tied to them.

We've managed to maintain and improve the Separation of Concerns that our application requires and should now be able to detach the various application components and run them independently of each other. We are also able to provide our View designers with mock data at design time, while maintaining loose coupling at runtime.

In the next chapter, we will thoroughly examine the essential topic of data binding, one of the very few requirements of the MVVM pattern. We'll comprehensively cover the wide variety of binding syntax, both long and short hand notation, discover why bindings fail to work at certain times, and get a better understanding of how to display our data exactly the way we want.
