C# / Objective-C Extendable Application (Application that can be modified through extensions) -

i'm looking extending c# application (and objective-c counterpart) allow user created extensions loaded , utilized.

the thought loaded extensions either 'decorate' output, or replace driving mechanism entirely. example, application working on outputs colors based off logic defined in each operating mode. decorator extension converting grayscale, or upping saturation, built-in mode generate color , extension modifies result. while driver extension deed own mode outputting colors on own.

what design paradigms work sort of problem?

the "managed extensibility framework" help lot c# version of app:
