Hi,

That is N-Tier desing application and EDMX is the best one that automaticllaly generate DAL and BLL for us from Microsoft.

Answer 2

Hi,

can't we use other instead of ado.net entity framework

From my experience ,you can represent your data using any type of data access layer, such as ADO.NET Entity Data Model, LINQ-to-SQL object model, CLR object, or a Web service.

I would like to suggest you to check the link below for an article which describes the data access layers of WCF RIA Services.

swapnil, there are few many ORM tools available in the market Linq to entities, linq to sql, Nhibernate , third party tools.

but above all, the EF is best and best with WCF RIA sevices.

Answer 4

Forget about EF and RIA.  You should definitely take a look at WCF REST services. I've been working with REST for a few months now and I love the simplicity and speed. You don't have to generate proxy classes and you can work with simple plain old CLR objects (POCO) on both the server and silverlight side. Throw me a line if you need a sample project.

Answer 5

yes please, i would like to have a sample project.

Answer 6

I think we ALL would ;-)   How about posting some stuff here or a link to somewhere with it.
