If your BLL is Web Service based then Model is used by BLL and DAL and the
UI uses the WSDL as an interface. WCF allows you to still use the model even
based on WSDL which is strange as somehow it must transpose namespaces. I
have not done much with WCF but it is interesting how it does this and I
wonder whether it could cause more issues than it solves.

Actually you are right Miha. I read some articles about them and theory is pretty clear, however implementation isn't that clear, for instance when I use controls like textbox to bind to fields there is no problem, but if I use a grid which can be editable the conection with the busines and data layers are kind of confusing. I'm sure that everyone deals with it in their own way, as I do myself, that is why I want to read other approaches to find better ways.

[please don't top-post] I'm developing a program but still having some issues to write a good layered program wich includes presentation, business, and data layers. Can some one suggest any good book, white paper, or article about it with case study and clear examples writen in c#. Is this a WinForms or ASP.NET or something else? What does that matter? A proper DAL should be able to be dropped unmodified into any .NET project - that's the whole point... -- Mark Rae ASP.NET MVP http://www.markrae.net |
