Solutions: Modular Monoliths

Here are the solutions to the exercises in Chapter 8, ​Toward Modular Monoliths through the Social View of Code​.

Detect Components Across Layers

There are several answers to this exercise, which indicates that there should be opportunities to reconsider the current class boundaries by extracting and representing a new set of abstractions. Just to give one specific example, have a look at the CategoryController.cs and the ManufacturerController.cs, which change together in 88 percent of commits. As you see in the top figure, an X-Ray reveals that they have a similar concept for pop-up adds, and that concept could be expressed in its own component and context.^[152]
