huysentruitw/Aggregator

This system is an event-sourcing framework for .NET that manages aggregate roots and their state changes. It provides a command processing pipeline that dispatches domain events and persists them to an event store. The library supports multiple dependency injection containers and includes a fluent testing API for verifying aggregate behavior.

How it got here

2018 · Architecture modernization and DI integration

The project underwent a significant architectural refactoring to simplify the core AggregateRoot implementation and introduce asynchronous, dependency-injection-friendly patterns. This period saw the migration of the test suite to xUnit, the introduction of a custom event dispatcher, and the addition of Microsoft.Extensions.DependencyInjection support alongside a new EventStore persistence layer.

2019–2020 · Testing infrastructure and sample expansion

This period focused on enhancing the framework's testability by introducing a fluent testing library for aggregate roots and expanding the Kanban sample with comprehensive domain and integration tests. Additionally, the KanbanStyle sample was augmented with a full ASP.NET Core and Angular 6 frontend template.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit d78423b561 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
