Hi I’ve been given the task of creating an N-Teir website using the Entity Framework 4 and am coming up against some brick walls, more than likely in my knowledge.
My plan so far was to have these layers
Website (application layer),
What I’m calling Name.Framework (BLL),
Name.Data (DAL),
Name.Entities (contains POCO classes and other struct classes used in website/bll,
Name.Common (utility class)
I’ve tried to use the repository class, but am struggling to make things work how I thought they would. Below are a few examples of what I’m getting stuck on.
If I want to use .include() would this be in my Repository or is this the responsibilty of the business layer? (and I have no idea how this would work in the BLL)
Same question for .Order()? As I understood it this would need to be in repository or at least passed into the repo in some way?!?
Should I be using the BLL to pass in the Context to the repository/data layer? At the moment when I get an entity from the Data layer any navigation properties that weren’t referenced in the repo just come back with ‘Object Context Disposed’, should the Business layer still hold the context etc so that this wouldn’t happen?
Or to summarize this HELP!!!
I need to have this in some sort of order by tomorrow (eek!) as the project leader wants to know if we are going to continue with Entity Framework or move to NHibernate as in-house we have more knowledge of it.
Thanks for any help or suggestions
Matt
Looking for something similar myself I found this. Not looked into it too much at the moment but looks promising.
