Sorry about the not so clear comments above, if you can delete them. It didn’t give me option to delete.

I was trying to copy paste the default IRepository implemenation and to ask you compare it with having individual interfaces.

public interface IRepository : IDisposable{ T[] GetAll(); T[] GetAll(Expression<Func> filter); T GetSingle(Expression<Func> filter); T GetSingle(Expression<Func> filter, List<Expression<Func>> subSelectors); void Delete(T entity); void Add(T entity); int SaveChanges(); DbTransaction BeginTransaction();

Thanks,

Why not just create the generic IRepository interface and just override it with the specific implemenation.

public interface IRepository : IDisposable
{
T[] GetAll();
T[] GetAll(Expression<Func> filter); T GetSingle(Expression<Func> filter); T GetSingle(Expression<Func> filter, List<Expression<Func>> subSelectors); void Delete(T entity); void Add(T entity); int SaveChanges(); DbTransaction BeginTransaction();}Is this a DAL or a repository? In this case I guess its both.
