LLBLGen Experts where are you


Hello to seniors and LLBLGen experts, I am building a web application using asp.net 3.5, sql server 2008. My client wants it to be in minimum 3 tier architecture(Tiers are seperated physically, means 3 tiers means 3 seperate machines).

User Interface Tier: All the pages will be deployed on the different web server. This server will host only and only asp.net pages or server components.

Application Tier: This server will host the business logic and this is the tier where all the business logic will be implemented and deployed. This tier will fill the communication gap between database and the User Interface(UI).

Database Tier: A seperate server will be utilized to host the database only.

So far so good.

Actually my client is willing to use LLBLGen for the boiler plate code generation and to make the development fast.

My issue is that how can I call the components available at application layer from asp.net (user Interface layer)pages, because these application layer components are suppose to talk between the database and UI.

I have developed apps using the logical seperation where UI and BL is on the same machine(without LLBLGEN). But on the different machines I am going to do it for the first time.

So please please kindly help me on achieving this 3 tier scenario and if there is any good tutorial or article available kindly share it please.

If this question seems idiotic, then kindly accept my appology.

All the comments and suggestions are welcome.

Thanks and regards.

You need to use WCF (Windows Communication Foundation), to communicate between Application Tier and Presentation Tier.

Thanks walaa. Can you tell me WCF services are generated via LLBLGen along other code generation or not ?

You can start here.

Also the download section of the website has a complete WCF working example.
