Hi I`m trying to do something that seems kinda easy, and is documented that way but for some reason its not going that easy.
Basiclly I wrote something like this:
If you see the inheritance of class 'ActionFilterAttribute' that inherits "FilterAttribute, IActionFilter, IResultFilter" classes. The method you are looking is available in IResultFilter interface.
Therefore it never executes a method when we use custom class as an attribute. Always we need to override all IActionFilter and IResultFilter methods in-terms to custom implementation.
