Separation of report design and application

I'm working with Visual Studio 2010, and it's Winform application.

I made an application where i use Crystal Report as reporting tool, but everything is embedded in one single project...! until lately i read an article about structure of applications and separation of concerns and i realized how bad was the code i wrote !!!

So i started all over again, trying to build another version that contains many project, one of them will be the Crystal Report project (Library Class), I'm trying to make a separation of the report design and application, I did that already but i really don't think i am doing it the right, it's very ugly (I'm talking Pattern Design Side) !

I don't have any experience in Design Pattern or Architecture so Can you please show me the right way to create my CR report Library Class and how to bind it to the main Project and call it ?

NB : i know this question is too wide, and it can be closed because it's against the rules of Stack-overflow, but please any hint is welcome !
