AI Assistance Disclosure

DxMessaging began as an original project around 2014 and remains actively developed and used today. Over the past two years, I (wallstop) have been using LLMs to help improve the library's quality and performance, expand its tests, and create user-facing documentation. There is always a human in the loop: I actively review all changes and read through all user-facing copy. I share this so you can make an informed decision about using the project.

DxMessaging is free and will remain free forever. No paid editions, paid upgrades, or feature charges.

Why Teams Use It

Simple primitives

Choose untargeted, targeted, or broadcast messages. Senders and receivers share a typed message contract.

Easy to use

Define a message, register a handler, and emit. MessageAwareComponent owns registration cleanup through its Unity lifecycle. Plain C# owners enable and dispose their registration tokens.

Small edits, big impact

The same simple primitives decouple entire systems. Wiring a feature in is one registration; removing it is deleting that line. Interceptors, handler priorities, and global observers layer on without touching existing code.

High performance

Ordinary typed steady-state struct dispatch is allocation-free. Global accept-all handlers box structs, and emission-site stack-trace capture allocates. See the performance page for measured scenario costs.

See the Reference-Faq#does-dxmessaging-allocate-memory-is-dispatch-zero-gc before choosing a dispatch path or enabling diagnostics.
