Question

I am following one of the example from http://kazimanzurrashid.com/posts/entity-framework-code-first-bootstrapping

In that post Kazi used Ninject but in my case I choose Unity as my IOC container.

I am finding difficuty in translating the following niject module code in to Unity code. All the help will be apreciated.

public class DataAccessModule : NinjectModule
{
    public override void Load()
    {
        Bind<DataContextFactory>()
            .ToMethod(c => new DataContextFactory("DefaultConnection"))
            .InRequestScope();

        Bind<DataContext>()
            .ToMethod(c => c.Kernel.Get<DataContextFactory>().GetContext());

        Bind(typeof(IRepository<>)).To(typeof(Repository<>));
        Bind<UnitOfWork>().ToSelf();
    }
}

Thanks in advance!

Try this for the registration

public class DataAccessModule : UnityContainerExtension
{
  protected override void Initialize()
  {
    this.Container.RegisterType<DataContextFactory>(new HttpContextLifetimeManager(), 
      new InjectionFactory(c => new DataContextFactory("DefaultConnection")));
    this.Container.RegisterType<DataContext>(
      new InjectionFactory(c => c.Resolve<DataContextFactory>().GetContext()));
    this.Container.RegisterType(typeof(IRepository<>), typeof(Repository<>));
  }
}

A sample for the HttpContextLifetimeManagercan be found here.

You need to add the DataAccessModule to your container in your composition root.

container.AddNewExtension<DataAccessModule>();
