Automapper error after updating a record with POCO classes, Unity and EF6


Automapper error after updating a record with POCO classes, Unity and EF6

hop of those help? Prior to initializing the mapper in global.asa i was doing this in the controller itself. I had failed to remove the line(below), from the controller, where the article record was being edited:
code :
 Mapper.Initialize(cfg => cfg.CreateMap<Article, ViewModelArticle>());

will help you First of all you don't have to write your CRUD inside POCO, There are many places where you can do it like in edmx.cs file or write one more layer which is called as CRUD Services which handles the Database operations using context object.
Now coming to your questions,
code :
EmployeeDepartmentModel
{
 prop EmpList List(Emp);
 prop DeptList List(Dept);
 //Emp and Dept are my POCOs
}
FillTheModel()
{
  EmployeeDepartmentModel.EmpList = EDMX.GetAllEmployees;
  EmployeeDepartmentModel.DeptList = EDMX.GetAllDepartments;
}

hop of those help? Definitely use DTOs + AutoMapper. Otherwise you'll have tons of problems with DataContractSerializer while using WCF due to circular dependencies (especially problematic with navigational properties). Even though you may omit DTOs initially, you'll be forced to used them later on due to problems mentioned above. So I would advice using proper DTOs for each tier.
Also your tier specific models will carry different attributes. You may also need to modify (i.e. specialize) the data that you carry up in each tier. So if your project is large enough (or have the prospect to be so), use DTOs with proper naming and place them in proper locations (i.e. not all in the same assembly).

like below fixes the issue That's the way entity works. Those classes will always be refreshed when you run the tool. To accomplish what you are trying to do you need to add the new properties or methods on a different file. The auto generated classes are marked partial for that reason. Here is a link of situation similar to yours http://robbincremers.me/2012/01/31/entity-framework-using-partial-classes-to-add-business-logic-and-validation-to-generated-entities/
