Now that we have described events, we note that, in general, method references are the only cases where it is advisable to work with a delegate variable outside the context of an event. In other words, given the additional encapsulation features of an event and the ability to customize the implementation when necessary, the best practice is always to use events for the publish–subscribe pattern.

It may take a little practice before you can code events from scratch without referring to sample code. However, events are a critical foundation for the asynchronous, multithreaded coding described in later chapters of this book.
