wmeints/efcore-ddd-demo

This system is a .NET 6 application designed to manage a bakery domain, specifically focusing on the creation and categorization of pies. It enforces strict business rules for pie ingredients, requiring them to sum to a specific ratio, and tracks serving portion constraints. The architecture separates domain logic from infrastructure, using Entity Framework Core to persist data about pies, their ingredients, and their categories.

The domain layer now includes the Category aggregate and the Pie aggregate. The Category class provides a simple entity with an ID and name. The Pie aggregate introduces a factory method for creation and an UpdateIngredients method that enforces business rules: ingredients must be provided, and their relative amounts must sum to exactly 1.0. The Pie also exposes a read-only collection of ingredients and links to a Category via CategoryId.

src/Domain · high confidence

The data layer now supports categorizing pies and tracking serving portions. A new Category entity has been introduced, requiring a CategoryId foreign key on the Pies table to link pies to their respective categories. Additionally, the Pies table now includes Minimum and Maximum integer columns to define portion ranges, and the database model has been updated with corresponding migrations and entity configurations to persist these new fields.

src/Infrastructure · high confidence

The Pie aggregate has been restructured to better model baking specifics. The original Pie entity, which only tracked name and description, has been replaced by a more detailed model that includes Ingredient records (capturing name, allergen status, and relative amount) and Portions records (defining minimum and maximum serving sizes). This change allows users to define precise ingredient compositions and serving constraints for pies, moving beyond simple textual descriptions to structured, validated data.

Domain · high confidence

The project has been reorganized into a standard src and tests folder structure, moving Bakery.Api, Bakery.Domain, and Bakery.Infrastructure under src, and their corresponding test projects under tests. An MIT License file has been added, and the README has been updated to reflect the new .NET 6 target and provide instructions for running the included unit tests.

(repo-wide) · high confidence

Added new test files covering the PieAggregate domain entities (Ingredient, Pie, Portions) and the Infrastructure layer's PieRepository. The domain tests verify validation logic for ingredient names, relative amounts, and portion constraints, as well as pie creation and ingredient updates. The infrastructure tests use an in-memory EF Core database to verify repository operations including saving, finding all, and finding by ID.

tests · high confidence

The project has been upgraded from .NET 5 to .NET 6 across the Domain, Infrastructure, and API projects. Additionally, the Microsoft.EntityFrameworkCore.SqlServer and Microsoft.EntityFrameworkCore.Design packages have been updated from version 5.0.2 to 6.0.7 to align with the new framework version. The API project no longer references these Entity Framework Core packages directly, as they are now managed by the Infrastructure project.
