Question

I created a simple CodeFirst (Entity Framework 4.1) context and then, using the right mouse button on the controller folder said : “Add Controller”, “Entity Framework”, picked one of my simple codefirst entities I created and the associated context. The controller code it genreated is as follows below.

What has me confused is why the Context is created as a private object in the Controller class. I would think that it should be create in a using() so that at the end of the method it could be disposed properly.

What am I missing here? I’m sure the guys who wrote this no what they are doing.

Thanks

namespace Web.Controllers
{ 
    public class TaskInfoController : Controller
    {
        private TaskContext db = new TaskContext();

        //
        // GET: /TaskInfo/

        public ViewResult Index()
        {
            var taskinfos = db.TaskInfos.Include(t => t.TaskGroup);
            return View(taskinfos.ToList());
        }

Well, this allows for atomic commits, but I agree, this is not the proper way. I use the Repository/Service/UnitOfWork pattern with MVC3 and EF and it works great. Search SO for it, there is a ton of info on it. In the meantime, move it into a using statement inside the controller action.
