public class MyClass { [LoggingAspect] public void MyMethod() { // Code that might throw an exception } } In this example, the LoggingAspect class inherits from OnExceptionAspect and overrides the CompileTimeValidate , GetExceptionType , and OnException methods. The aspect is then applied to the MyMethod method using the LoggingAspect attribute. When an exception occurs in MyMethod , the aspect will automatically log the exception and send a notification to the development team. postsharp

The problem was that the logging mechanism in his application was not working as expected. Every time an exception occurred, the application would log the error, but it would also attempt to send a notification to the development team. However, the notification code was scattered all over the application, making it a nightmare to maintain and debug. // Send a notification to the development team //
John had tried to use a traditional object-oriented approach to solve the problem. He had created a base class with a virtual method for logging, and then overridden it in each of his derived classes. But this approach was cumbersome, and he found himself duplicating code all over the place.
