• Great talk today in Building N-Layer Applications with LINQ. Wish there were more sessions on layering and how LINQ is going to simplify that.
  

• Hi,
  I was in your building N-Tier app with Linq session. I like the idea that you create data/biz class as separate tiers.
  My question is that which tier will you put the cache bit of code? What I mean is the cache of object such as dataset, not the page cache.
  I have been using n-tier for a long time but the problem is that every time we make a change in a DLL, it becomes a big job to update the entire apps since the dll is shared by many apps. Another issue is that many apps are written in different version of .net and some third party component are also used for certain version so it also make the global update harder.
  Sorry I didn’t catch your email in the show so I just post my question here.
  Thanks,
  Richard
  

• Re: source code for building n-layer. I attended the confernce and really enjoyed your presentation. Your demo showed a complete web app with the n-layer code. Did you intend to include the web pages and their code, because I can't find them with your posting?
  
  Thanks

• Great opresentsations, lots of substance and excellently presented!
  

• Great presentation, at the end of one of your sessions one of the persons in the row where I was sitting said you were the best presenter, I immediately agreed and all of those who heard about the comment did as well.
  
  thanks,
  

• Dan, "Building N-Layer Applications with LINQ" was a great session.
  It was so good that I wanted to download and try out your demo.
  
  I downloaded the zip file (N-TierWithLINQ), but the N-Layer web site only seems to have a single file in it (Northwind.ldf). Is there more, or am I doing something wrong?
  
  Thanks again for your presentation.
  

• Your demo showed a complete web site for the n-tier with link.
  I can't find .aspx pages for your source
  

• Sorry about the download problem. Not sure why the aspx files weren't zipped, but you'll find the complete application at the download link now.
  

• RichardT,
  
  It depends on who you talk to as far as caching goes. I feel that caching is a business/app rule so I normally set the cache duration and access the cache in the business layer. But, I could see people arguing that it's a data layer task as well. Just depends on how you want to look at it. I like to go to one place to change "rules" which is why I like to put it in the business layer.
  

• Alex,
  
  Thanks for taking the time to attend the session and comment. I'm glad to hear you (and the others near you) enjoyed the presentation. :-)
