Im currently trying to refactor a project(asp.net mvc) that doesnt have any separation at all. just folders :s

  • The project has a bunch of EF Code First classes (People.cs, Exam.cs,
    Message.cs, etc)
  • The project has several repositories (which all use EF Data
    Context)
  • And of course a lot of controllers and viewmodels

We have a Tests Project but we arent very good at TDD so its not something we are really working on as of now.

I would like to have a clearer separation on the different responsibilities that the project has to address and would appreciate some advice on a good project structure that achieves this.

Please help.
thanks in advance

    I would suggest following a Domain Driven Design (DDD) and one suggested way of laying this out would be creating the following projects:

    Company.Project.Web <– Your MVC Application, though you can still use WebForms
    Company.Project.Domain <– Data Transfer Objects (DTO’s), ViewModels, Business Logic, Events
    Company.Project.Data <– Repository Interfaces

    Company.Project.Data.EF <– EntityFramework Specific Implementation of Repositories
    Company.Project.Model <– Your EF CodeFirst Classes

    Company.Common <– A common project of utilities and/or extensions

    I would suggest you take a look at Project Silk http://silk.codeplex.com/ from the patterns and practices team. Great reference implementation of DDD, Repository, and MVC as well as mixing in HTML 5 and jQuery (vNext).
