As .NET monoliths evolve, maintaining a consistent and navigable codebase becomes a paramount challenge. Developers often find themselves repeatedly creating the same foundational folder structures and basic file outlines for new features, particularly when adopting vertical slice architecture. This manual scaffolding is not only a drain on developer time but also a breeding ground for inconsistencies, ultimately fragmenting the project and hindering maintainability and velocity. Claude Code addresses this common friction point by automating the generation of these modular feature structures.
Leveraging Claude Code via its CLI, you can rapidly scaffold a new vertical slice feature, drastically reducing initial setup time. Consider adding a “Product Catalog” feature. Instead of painstakingly crafting directories like Features/ProductCatalog/Application, Features/ProductCatalog/Domain, and Features/ProductCatalog/Infrastructure, along with their associated interface and implementation files, Claude Code streamlines this process. A typical command might look like this, where claude new feature initiates the scaffolding and ProductCatalog defines the feature’s scope:
claude new feature --name ProductCatalog --architecture VerticalSlice --output ./src/Features
This command instructs Claude Code to create the necessary directory hierarchy under ./src/Features for the ProductCatalog feature, adhering to vertical slice principles. It intelligently generates subfolders representing distinct architectural layers (e.g., Application, Domain, Infrastructure) and can even stub out common interface files. This automated consistency is invaluable for onboarding new team members and ensuring each feature is a self-contained unit, significantly lowering the cognitive load required to understand and work within the codebase.
A crucial consideration is that while Claude Code excels at establishing the structure, the generated files are intentionally stubs. You will still be responsible for implementing the actual business logic, domain entities, application services, and infrastructure integrations. Furthermore, the --architecture flag and its supported values are tied to Claude Code’s current feature set and documentation. For projects with highly bespoke naming conventions or specific boilerplate requirements within each generated file, you may need to manually augment the stubs or investigate Claude Code’s extensibility options if they exist.
To experience this firsthand, navigate to your .NET project’s root directory in your terminal and execute claude new feature --name UserProfile --architecture VerticalSlice --output ./src/Features. Observe how a new, well-defined folder structure for user profile management is instantly created, freeing you to focus on the core business logic rather than repetitive setup tasks.
