    Chain of Command is the thing that allows you to write method extensions and call next in them. Then you'll get several methods (of the same name) that are called in sequence instead of the single original method.

    Class extensions are a more general concept. For example, if you add a class extension method, add a class field or an event handler, you're extending a class but you're not using CoC.

    Also, check out documentation: Class extension - Method wrapping and Chain of Command.

    Hi,

    A class extension and CoC are used together.
