Hey guys,

I'm looking to improve my knowledge of design patterns and n-tiered
application architecture.  Do any of you have any suggestions on good reading
material?

I know the GoF book on design patterns is very popular but I was wondering
if that is my best choice to learn these design patterns.  It is a pretty old
book and in C+, and I am concentrating on C# but I don't think that would be
a problem.  However, if anyone knows a book thats just as good as the GoF one
and in C#, please let me know.

Besides desing patterns, I would like to learn more about n-tiered
architecture and application development (winforms and soon WPF).  Any
suggestions for this (C# preferred)?

Thanks for the input,
