To add to your list:

A great detailed book on C# (I've read about half of it so far, and just from a couple examples of things that might not work how you expect, that will keep you debugging for hours, this book is well worth it):

The design pattern book you pointed out looks very promising. If someone wants a very good start. This book is in Java, but the examples can be very easily ported to C#. I know in the last codecamp I was at, they used this book for a design pattern session:

>Thanks Kevin. I'd really appreciate your input. Enjoy dinner! :o)

>Thanks - had ribs and Guinness and then a new HP desktop for desert (for real! it's a screamer)

>First, yes, the C# Cookbook is very good (as are most O'Reilly titles)
>
>Anything by Jesse Liberty is likely to be very good.

>Somewhere along the line, I think someone recommended the Christian Nagel C# 3.0 book from Wrox. This is something I would have said before joining Apress - be careful of Wrox titles, especially those with multiple authors (Christian's book has 5 listed authors). Wrox has been producing some titles with big quality and continuity issues, and most occur with multiple authors. Some Wrox titles are very good, but some Wrox titles have many, many errors in them.

>In my view, one of the best C# 3.0 titles is Andrew Troelsen's C# 3.0 book:

>I think Craig mentioned Juval Lowy, and I agree, his books are good (his material is not intro material, so yes, you'll need to establish a foundation first).
>
>Truth be told, with all the blogs that exist, it's becoming easier and easier to find blogs and websites that cover a good % of the same material that exists in books.

>Now, here are two that I was able to review, and will be out in a few months:

>First, a very good book on LINQ:

>Second, Andrew Troelsen is working on a 3.5 update for his book:

>Finally, here's one that I know nothing about, but plan to keep my eye on:
