Create ASP.NET plugins in my Application

Question

Hello,

I'm trying to create an application that has configuration about the modules that should be loaded. For that I have a Theme engine that can be configured by the client with what modules what to load and where to load.

This modules can be developed by any other team in the company and each time we have a new version of the plugin or anytime we want to to develop a new plugin we don't want to send the source code.

How to create plugin and develop a web site using that plugin.

Any solution for this?

Please give me idea from where i have to start?
