Check out "Doing Objects in VB2005" by Deborah Kurata, even if you are a C#
programmer (you can figure it out). It was just published.
It explains the main layers (presentation, business, and data access) and
how to separate your code. It's a soup-to-nuts book, but practical and
understandable, with a real-world example. It starts with designing your
classes and goes through UI and on into the Data Access layer, and you end
up with a whole application split into 3 layers.
If you want a more complicated approach, google Rockford Lhotka and check
out his books/website.
..Net 3.0 = .Net 2.0 + (WPF + WCF + WF) When people talk about .Net 3.0
development, they are generally talking about WPF, WCF, or WF.

How many layers are in .net application development? I have seen the
following layers mentioned in various resources:
Presentation Layer
Workflow Layer
Business Layer
Data Access Layer
Data Layer
Are there any good articles/webcasts to explain each layer? Is any of
them
optional? Which layer should be built first? Is this layer concept same
in
both .net 2.0 and .net 3.0?
