tonyx/Sharpino

Sharpino is an event sourcing framework for .NET that provides the core infrastructure for building domain-driven applications using F#. It enables the management of aggregate state through event streams, supporting both in-memory and PostgreSQL-backed persistence with optimistic concurrency control. The system facilitates distributed caching via Azure Service Bus or Redis, ensuring cache consistency across multiple application instances. Additionally, it offers a comprehensive suite of sample applications demonstrating various domain models, command handling, and integration patterns.

How it got here

2023–2024 · Event sourcing and sample expansion

This period focused on establishing the core event sourcing infrastructure and expanding the library with distributed caching and optimistic locking capabilities. The team simultaneously developed a wide array of sample applications, ranging from simple todo lists to complex stadium booking and pub management systems, each demonstrating different aspects of the framework.

2025 · sample applications and optimistic locking

This period focused on expanding the framework's documentation and capabilities through a series of new sample applications, including shopping carts, transport tycoon, and course management systems. Concurrently, the database schema was significantly updated to support optimistic locking and multi-stream consistency checks, ensuring data integrity for all new aggregates.

2026 · Optimistic locking and cache synchronization

This period focused on implementing optimistic locking mechanisms across various sample applications to ensure data consistency in concurrent event store operations. Additionally, the work expanded caching strategies by introducing L2 cache support with both PostgreSQL and Redis backends, enabling multi-instance cache synchronization via message systems.

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 29 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit c11e14761b — 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.
