If you are going to use an IoC container, regardless of which one, here is what needs to be registered, and some thoughts about object lifetime. If we do not specify a lifetime, you can assume that singleton is acceptable.

Highway.Data

• IRepository should resolve to Repository on either a transient (new every request) or per web request (if you’re in a website) object lifetime.
• IEventManager should resolve to EventManager
• ILog should resolve to either a Common.Logging implementation for your chosen logger, or an instance of NoOpLogger from Common.Logging.

Highway.Data.EntityFramework

• IDataContext should resolve to DataContext on either a transient (new every request).
  • Your IoC will need to inject a connection string, named connectionString to the constructor, in whatever way such primitive dependencies are handled by your container.
• IMappingConfiguration should resolve to a type you have created that implements this interface and maps all of your entities.
• IContextConfiguration should resolve to DefaultContextConfiguration or a class you’ve created should you need to change how the Context is configured from our defaults.

Highway.Data.NHibernate

• IDataContext should resolve to DataContext on either a transient (new every request).
• ISession should resolve to a call to your configured ISessionFactory. These are standard NHibernate interfaces, and you should follow their guidance regarding object lifetime.

Highway.Data.RavenDb

• IDataContext should resolve to DataContext on either a transient (new every request).
• IDocumentSession should resolve to a call to your configured IDocumentStore. These are standard RavenDb interfaces, and you should follow their guidance regarding object lifetime.
