What are light events?

Question

Earlier, several times the term came lightweight event. The texts were not accompanied by code fragments in order to understand the idea of ​​this term.
I would really appreciate it if someone could explain what easy events are and give an example.

Answer 1

When you add an event handler to an event (or a group of methods to a delegate, really), the delegate will contain a reference to the object in which the group of methods is included, if it is an instance method.

In other words, the object that triggers the events will be held on your object that receives events when it is subscribed to the event.
