# mono-addins Mono.Addins is a framework for creating extensible applications, and for creating libraries which extend those applications. Mono.Addins has been designed to be easy to use and 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. This new framework intends to set an standard for building extensible applications and add-ins in Mono. Main Features The main features of Mono.Addins are: * Supports descriptions of add-ins using custom attributes (for simple and common extensions) or using an xml manifest (for more complex extensibility needs). * Support for add-in hierarchies, where add-ins may depend on other add-ins. * Lazy loading of add-ins. * Provides an API for accessing to add-in descriptions, which will allow building development and documentation tools for handling 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. * 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.
