Derived Decorator: Auto-set Properties (C#)
Here's an example of auto-setting properties in a pseudo-decorator pattern in C#, where the decorator is a derived class that automatically sets properties on its base class.
This is somewhere between a decorator and a wrapper or facade. For straight forward cases it saves the work of manually setting properties of the base class from the instance passed in on the constructor.
