Optional OOP/C# language features explanation

[nbarbettini]

@Welkie had a great suggestion here:

I think it would be a good idea have a section with an intro to OOP concepts, maybe with a disclaimer that it's an optional section that can be skipped if readers are already familiar with OOP.

It may also do double duty as a nice intro to C# language features too, which means there would be less need for comments about C# features in the rest of the book (for example, talking about the constructor, or a generic type), making the rest of the book flow nicer. In this case, the section would be best pitched as an "intro to OOP concepts in C#" so that both those new to OOP and new to C# would know to read it first before continuing.

Glad to hear you like the suggestion. I will probably have time to help you write this section once my semester finishes up in a few weeks, so I'll keep it in mind.

Appendix might be the best place for explaining OOP that should be also regarded as an out-of-scope topic in this book.
