A typos in article erfan razi Dec Member Nice article but this is not about 3-tier - this is about 3-layer architecture Azamat Kurbanaev Mar 6: Azamat Kurbanaev. See comments of another copy of this article here. Simple, yet effective explanation Member Jan 6: Very simple, yet insightful article. Thank you for sharing your vast knowledge.
Should we add layers as new project and class library? Ammar Shaukat. You talked about "Data Access Layer" and "Business logic layer". Are you adding these two layers as a new project to solution or one have to add a class library as new project in solution? My vote of 5 Prabin Siwakoti Apr 1: I have some forms which stores data and some reports. I have decided to use WPF for the purpose. I am new to WPF, so needs help. I need some sample application of WPF which stores the data in database using 3 tier architecture. I think that unless the benefits of having application tier on a different computer are significant, you should keep it on the same computer and use it as a library directly from your presentation code.

IServices; using BLL. GetAuthors ;. But where did I get the concept of using a Service layer? It's a concept that I got out of a Model View Presenter design pattern tutorial many years ago. It's a no fail solution. And I introduced the DAL into the pattern with everything based on Interfaces used by each object in the layers to implement the Interface contract between objects, just like in the tutorial.
