Brad Abrams and Krzysztof Cwalina's new book Framework Design Guidelines : Conventions, Idioms, and Patterns for Reusable .NET Libraries is available for preorder on Amazon. The last book Brad Abrams authored, .NET Framework Standard Library Annotated Reference, Volume 1: Base Class Library and Extended Numerics Library, is excellent and I have it sitting on my desk right now. Volume 2 in the latter series (often called the SLAR), .NET Framework Standard Library Annotated Reference, Volume 2 : Networking Library, Reflection Library, and XML Library is also available for preorder.
Get your favorite geek this gift today! Note that your favorite geek can certainly be yourself, I mean, it's just narcissism, don't let it get to you. It's ok, really.
