Polymorphism is a great thing. .NET, Java, C++ and other folks have enjoyed its benefits for a long time, some more than a quarter century already. Meanwhile, we, the meager C/AL bunch, can only dream about it and draft our little patterns that all come short of it if only by a tiny bit.
When you reference a .NET class that exposes events, and you switch on the WithEvents property, C/SIDE creates the event triggers for you. If you later want to update the reference to the .NET class, for whatever reason (like, there is a newer version of the assembly), updating the reference will actually delete the event triggers with all the code in them.
