According to the Common Closure Principle, how should features that contain shared functionality be structured?

According to the Common Closure Principle, features that contain shared functionality should be organized in a way that allows for cohesive maintenance and management of related components. When you place the website and commerce Visual Studio projects into one Feature module, it ensures that any changes made to shared functionality can be performed in a single place, reducing the risk of inconsistencies and dependencies scattered across multiple modules.

This organization enhances maintainability because it groups related functionalities together, allowing developers to manage and test them in a unified manner. By having a dedicated module for these interconnected components, it simplifies deployment and updates, ensuring that the shared functionality is always aligned across both the website and commercial aspects of the application.

In contrast, splitting projects into multiple projects or modules may lead to complexities where developers have to address dependencies separately, making it harder to ensure that all related features are functioning seamlessly together. Placing both the website and commerce projects in a single module directly aligns with the principle's goal of reducing the coupling of changes and promoting modularity across related features.
