I come from Access and VBA development and now trying to get into the OOP. My role is going to develop the data centric applications most probably WPF browser based. My first task is to convert the Performance Management System to C#, WPF.
Can you please give me a good example to use N-Tier applications? I want to use class libraries and want to write my own logic (i don't want wizard or EF model).
Also for the data centric applications will i need to use interfaces, delegates?
