Arbiter Project

Arbiter is a comprehensive .NET library suite that provides robust implementations of the Mediator pattern and Command Query Responsibility Segregation (CQRS) patterns. Designed for modern .NET applications, Arbiter enables clean, maintainable, and scalable architectures including Vertical Slice Architecture.

Overview

Arbiter consists of multiple focused libraries that work together to provide a complete solution for building modular applications:

Core Libraries

  • Mediation: Lightweight mediator implementation for decoupled request/response handling
  • Command Query: CQRS framework with pre-built commands, queries, and behaviors
  • Communication: Message template system for email and SMS services

Key Features

  • High Performance: Optimized for minimal allocations and maximum throughput
  • Extensible: Pipeline behaviors and customizable handlers
  • Architecture Support: Perfect for Clean Architecture, Vertical Slice, and CQRS patterns
  • Observability: Built-in OpenTelemetry support for tracing and metrics
  • Type Safe: Strong typing throughout with comprehensive generic support
  • Multi-Database: Support for Entity Framework Core, MongoDB, and more
