Question

I’m planning to create a web application using MVC 4 Single page application and I will use database first approach. And I’m using the default Sql Server LocalDB (with the login/authentication tables).

Where should I put the edmx file? Under the Model folder? What if I want to have a service layer/repository layer.

BTW, the default template of SPA create two classes for each model, for example TodoList.cs and TodoListDto.cs. Why and is there any better design to avoid two classes?

Answer 1

I like to start by creating a {DataLayer}-Project.

1. Add the EDMX file to your {DataLayer}-Project
2. Add a references (under references) from your main project to your {DataLayer}-Project
3. add using {DataLayer}-Project; in every file that makes reference to your Entities

When my project achieves optimum maturity, I change my {DataLayer}-Project into a service.
