[echoix]

In the page How to declare, instantiate, and use a delegate - C# Programming Guide, there is a section named Robust Programming, but it isn't introduced and for a first time reader, it's difficult to understand what is "Robust Programming" that is being talked.

A sentence or two explaining the section that will be talked (what it does, or why following the following is important) would be helpful.

I've added this to our backlog for our next update to this article

Later I saw that this pattern of "robust programming" was repeated other sections in the equivalent articles. It could be in the backlog too.
