There's an old WROX book on pattern which follows this approach.  This is in VB.NET, but it shouldn't matter.  Not sure whether a c# copy is available or not.  It can be procured from

I had read this couple of years back and found it very useful as it deals with some real stuff and is definitely a good read after Head first patterns.
