pardeike/Harmony

Harmony is a .NET library for runtime code patching and modification, enabling developers to inject, replace, or modify existing methods and IL code at runtime. The system provides a comprehensive API for patching, reflection, and IL manipulation, supported by a modernized architecture that includes fast reflection helpers, serialization, and robust testing infrastructure.

The project underwent a significant structural reorganization, splitting the library into distinct Thin, Fat, and Reference assemblies while centralizing build configurations. Concurrently, extensive test coverage was added for the new helper classes and refactored reflection utilities, ensuring robustness across the updated codebase.

The project underwent a major architectural restructuring to support version 2.0, introducing a shared project file and explicit internal visibility for better build organization. This period focused on refactoring the public and internal APIs to support new patching types and state management, accompanied by comprehensive unit tests for IL parsing, reverse patching, and transpiling.

This period focused on modernizing the codebase by migrating patch serialization to System.Text.Json and forwarding Mono.Cecil types to improve compatibility with modern .NET versions. Concurrently, the project expanded its test coverage with new libraries and isolation techniques, while significantly restructuring and expanding the official documentation to guide users through patching workflows.
