Part 10: Plugin System Architecture - Extensibility by Design

Our workflow engine is designed to be more than just a pre-defined set of nodes. We recognize that every business, every API, and every integration is unique. That is why we built Vyshyvanka around a robust, assembly-based plugin architecture that allows you to extend the engine without touching the core codebase.

The Foundation: Assembly Loading

At the heart of our extensibility model is .NET's AssemblyLoadContext. When the engine starts, the PluginLoader scans a designated plugin directory for compiled .dll files. Each plugin gets its own collectible PluginLoadContext, which provides full isolation from the core application — preventing version conflicts between your dependencies and the engine's dependencies.
