Hi,
I suggested the first. Thought of suggesting the second. But I'm not sure about using an Extension method.
I know it would work but MS seem to recommend against them when there are alternatives.
Great if you don't have access to the source of the targeted class but, in the end, they are really just syntatic sugar?
Best,
