Last October I spent learning WPF and digging into C# internals. This break (yesh only two weeks left!) I'm trying to focus on Agile Development, Design Patterns (in C#) and WCF. I've picked up a few books and have already drilled into a few chapters of each. I'll let you know what my final thoughts on the books are when I finish them, though so far they have well been worth the purchase.
Programming WCF Services - Juval Löwy
Agile Principles, Patterns, and Practices in C# - Robert C. Martin, Micah Martin
Design Patterns in C# - Steven John Metsker
