RuntimePluggableClassFactory

This library has been made to make dependency injection at runtime. The main idea is to use a plugin folder from where the factory can load dll's. Factory that loads classes from provided assemblies having a specific user implemented interface inheriting from the provided IPluginClass interface.

Why use it and where

  • Websites/APIs that are running without persisted session state behind a login
    • As Asp.Net is implemented with compiled code the website will reload when a new dependency injection needs to be reloaded causing all session state information to disappear and typically logged in users will be expelled
  • Separating much modified extensions from the running code when making a program execution framework so that
    • application can internally contain the Continouos Deployment approval
    • extensions can be loaded and replaced at runtime
    • making it possible to make a/b testing for services
    • extension loading errors are not taking down the whole application and only the affected extension
    • making it easier to test extensions separated from other concerns

Design

  • You call a class factory (PluginClassFactory) to get a specific instance of a class

State

  • I have used it for a couple of projects which run in production

TODO

  • Include documentation on how to use the library as it is only existing in code right now
  • Massively extend the unit and integration testing
  • Assembly loader based on Nuget
    • Automatic updates support
    • Triggered updates support
    • Use Semantic versioning so that 1.2.x will return the latest as it is only corrections without breaking changes
    • Investigate if Semantic versioning only makes sense for interfaces and not for implementations
  • Unload ApplicationLoadContext when not any longer in use
  • Perhaps use the (Dot Net Tools)[https://github.com/RicoSuter/DNT] to switch between project and nuget references if I can get it to work in GitHub Actions
