With our first practical application, we've taken the theoretical ideas discussed in previous chapters and shown how they apply to the creation of a useful code base. From analysis to what the customer really needs to see, whether we can fulfill their request to sketching out designs, and undertaking short code spikes down to applying the MVVM pattern via view models and their supporting infrastructure, we've built an application brain-first rather than code-first.

In the next chapter, we'll create a more complicated real-world application, but this time, we won't have to discuss the basics of data binding in so much detail. We'll apply our growing knowledge to build a more complex app, a log analyzer, which could be used by a system administrator to monitor their infrastructure. This will require more thought about how to design the various moving parts that will make up our second application.
