Sorry, what are you asking? How to comunicate between layers?

Hi there,

You may want to take a look here: http://imar.spaanjaars.com/QuickDocId.aspx?quickdoc=476

It's not *the* link, but it's at least "a link" on N-Layer design.

In addition to Imar's excellent article, Wrox has a very nice book all about building an n-Tier ASP.NET solution:

As well as these two very useful but shameless plugs, there is the official Microsoft guide to creating n-tier applications. See http://www.codeplex.com/AppArchGuide
It's not exactly light reading, but it's given me a few ideas in the past, and is apparently based on much of the best practice actually used there.
(Of course, I'm sure the Wrox book is far superior, so that should be your first choice [;)])

n-tier application
Hi, there,

I have a question regarding/ implementing n-tier application
How can i create a layer?

1. is it put in the app_code folder?
or a separate class library.
2 what is the most advantage between
layer in putting app_code or a different class library

Hi there,

Separate layers don't have to be in separate projects, although they typically are. By putting your code in separate libraries, they become easier to version, update and maintain. However, you could put everything in a single App_Code folder (if using Web Site Projects) or some other folder (when using the Web Application Project model) and still speak of a layered application.

The article series I linked to show how to do both. The 2.0 articles are using App_Code while the 3.5 articles use a separate App_Code folder.
