Wiring up events from dll loaded at runtime?
<p>Basically I want to be able to write a dll for my application  that I will be able to put in a specific folder using a specific name and at runtime have that dll loaded and subscribe to a specific event.
As an example I have a simple Windows Form App with a single button on it. I want to be able to have a MessageBox displayed when the button click event takes place but I want the displayed message to be controlled by an external dll that is loaded at runtime.
What would be the best way to accomplish this?   </p>
