addin framework for extensible CLI applications/libraries Mono.Addins is a framework for creating extensible CLI 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. This package contains the Mono.Addins assemblies.
