Linq to SQL with WCF in a Multi Tiered Environment – Part 1

In many places, forums, blogs, or techy talks with some colleagues I hear some ongoing urban legends about Linq to SQL I came across: * You can not implement multi tiered applications with Linq to SQL * Linq to SQL can not be used for enterprise level applications I can’t say that both of these statements are particularly wrong or right, of course Linq to SQL can not handle every scenario but in fairness it handles most of the scenarios sometimes even better than some other RAD oriented ORM s. In this post I will create a simulation of an enterprise web application, having its Data Access, Services, and Presentation Layers separated and let them communicate with each other (err.., at least from service to UI) through WCF – Windows Communication Foundation.
