Okay, I have a question. I understand how to build user and composite controls, and how to add them to the toolbox and use them at runtime and design time. What I'm working with, for the first time, is a control extension. I need to create a minor modification to the standard .NET label control... I want to extend the class to add a property and the new functionality based upon that property. I can do that by making a class and inheriting from Label, then adding my new functionality, but once it's written, how do I use it in my applications?

So, how do I make and use a control extension?
