Any object capable of raising an event is an event sender, also known as an event source.

Removing an event source does not remove the underlying event handler from source text.

The class that raises an event is the event source, and the methods that process the event are the event handlers.

Therefore, you will get a compiler error if you delete an event source but leave the underlying function in the source code.

To resolve this problem, a user who has administrative rights must create the event source before you run the ASP. NET Web Application.

An event sink implements the interface and an event source consumes it.

Before writing an entry to an event log, you must register the event source with the event log as a valid source of events.

By using the Observer design pattern, you ve reduced the coupling between the event source and listeners.

Then use the connection point mechanism to connect the sink interface to the event source.

Managed classes that sink events do so by passing a delegate to the event source, instead of using COM connection points.
