Mono.Addins is a generic framework for creating extensible applications, and for creating add-ins which extend those applications. This framework has been designed to be useful for a wide range of applications: from simple applications with small extensibility needs, to complex applications which need support for large add-in structures.

The main features of Mono.Addins are:
  • Supports descriptions of add-ins using custom attributes (for simple and common extensions) or using XML manifests (for more complex extensibility needs).
  • Supports extension metadata and data-only extensions.
  • Support for add-in hierarchies, where add-ins may depend on other add-ins.
  • Lazy loading of add-ins.
  • Dynamic activation / deactivation of add-ins at run time.
  • Allows sharing add-in registries between applications, and defining arbitrary add-in locations.
  • Allows implementing extensible libraries.
  • Supports add-in localization.
  • Provides an API for accessing to add-in descriptions, which will allow building development and documentation tools for handling add-ins.
  • In addition to the basic add-in engine, it provides a Setup library to be used by applications which want to offer basic add-in management features to users, such as enabling/disabling add-ins, or installing add-ins from on-line repositories.
