I don't know if the intended for the list to be an audience of experienced .NET programmers who already write quality code.

However, he didn't qualify his "top 10" books which one could interpret as the 10 most important for any audience. If that's the interpretation, I propose a much different list which I think is more universal and applicable for a top-10:

CLR via C#, 4e, By Jeffrey Richter (If a person on the team is writing low-level foundation components, the knowledge in this book is a must. Otherwise, most C# developers writing line-of-business code can skip it.)

[In other words, I would substitute 7 of the article's suggested top-10 books with the ones above. If education time is limited, I'd rather a developer read the 2 Bill Wagner "Effective C#" books as priority over the Martin Fowler "Patterns" books.]
