Can a module consist of one or more Visual Studio (VS) projects, and should projects for one module always be managed together?

A module in Sitecore can indeed consist of one or more Visual Studio projects. This structure allows developers to organize their code within a logical framework that corresponds to the functionalities of the module. By having multiple projects within a single module, developers can separate concerns, such as having one project for data access, another for business logic, and yet another for user interface components.

Managing projects for one module together enhances collaboration and ensures a more cohesive development experience. It makes it easier to manage dependencies, as well as simplifying the deployment process. Since the module represents a specific set of functionalities or features, keeping its related projects combined ensures that the code remains maintainable and scalable. This organization aligns with best practices in software development where modular design is encouraged for clearer structure and reusability.

Considering the context, while it is technically possible for modules to be split across projects and managed individually, doing so may lead to complications in dependency management and increase the risk of discrepancies or inconsistencies within the module’s functionalities. Hence, it is advisable to manage these related projects together within a module.
