MessagePipe is a high-performance in-memory and distributed messaging pipeline library for .NET and Unity. It supports pub/sub, mediator pattern for CQRS, EventAggregator-style ViewModel decoupling, and IPC-RPC with a dependency-injection-first design.

Use cases

• publish and subscribe to typed events in .NET applications
• decouple ViewModels with an EventAggregator pattern
• implement mediator pattern for CQRS
• communicate between processes with IPC-RPC
• build distributed messaging pipelines
• replace slow C# events or Prism EventAggregator with a faster alternative
• manage event subscriptions in Unity games

When to choose

• you need high-performance pub/sub messaging in .NET or Unity
• you want DI-first messaging integrated with Microsoft.Extensions.DependencyInjection or VContainer
• you need sync/async, keyed, buffered, or scoped messaging variants
• you need interprocess or distributed messaging with the same API

When to avoid

• you need a full message broker with persistence like RabbitMQ or Kafka
• your project does not use a dependency injection container
• you need messaging outside the .NET/Unity ecosystem
