Functional Programming in C#

For those interested, I found this article and related tutorial from Eric White to be quite fascinating. I went through the tutorial this weekend and thought some of you might also be interested. Eric gives reasons for using functional programming (fp) over conventional object-oriented programming (oop); his most common reason is for performing transformations of data from one sort to another. Other highlights are more in-depth looks at extension methods, Linq and Office Open XML. (While you might wonder why you’d use fp instead of XSLT, the concepts can also apply to transforming objects/collections to other objects/collections using lazy evaluation and deferred execution).
