In this chapter, we will investigate application frameworks and the benefits that they can bring us. We find out the differences between providing this functionality via base classes and interfaces and also discover other ways to build the functionality into our frameworks. The chapter will finish off by investigating a variety of techniques to ensure that our applications maintain the essential Separation of Concerns that MVVM provides.
