How to use context.Set and context.Entry, which ships with EF4.1 ?

Hello,

I am trying to implement a generic repository as explained on the following link :-
http://www.asp.net/entity-framework/tutorials/implementing-the-repository-and-unit-of-work-patterns-in-an-asp-net-mvc-application However, I do not have options for context.Set or context.Entry, which Ships with EF 4.1 - is there some other way of doing it ? Please see problem code in bold below:-
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Data; // for EntityState using System.Data.Entity; using System.Linq.Expressions; // for Expression command using TasPOMark4.Models; namespace TasPOMark4.Models { public class GenericRepository<TEntity> where TEntity : class { internal TasEntities context; internal DbSet<TEntity> dbSet; public GenericRepository(TasEntities context) { this.context = context; this.dbSet = context.Set<TEntity>(); } public IEnumerable<TEntity> Get( Expression<Func<TEntity, bool>> filter = null, Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null, string includeProperties = "") { IQueryable<TEntity> query = dbSet; if (filter != null) { query = query.Where(filter); } foreach (var includeProperty in includeProperties.Split (new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries)) { query = query.Include(includeProperty); } if (orderBy != null) { return orderBy(query).ToList(); } else { return query.ToList(); } } public virtual TEntity GetByID(object id) { return dbSet.Find(id); } public virtual void Insert(TEntity entity) { dbSet.Add(entity); } public virtual void Delete(object id) { TEntity entityToDelete = dbSet.Find(id); Delete(entityToDelete); } public virtual void Delete(TEntity entityToDelete) { *//below Context.Entry does not exist* *//if (context.Entry(entityToDelete).State == EntityState.Detached)* *//if(context.ObjectStateManager.GetObjectStateEntry(entityToDelete) == EntityState.Detached)* *//{* dbSet.Attach(entityToDelete); //} dbSet.Remove(entityToDelete); } public virtual void Update(TEntity entityToUpdate) { dbSet.Attach(entityToUpdate); *//context.Entry does not exist* *//context.Entry(entityToUpdate).State = EntityState.Modified;* // GR skinning a cat (06/05/2011) context.ObjectStateManager.ChangeObjectState(entityToUpdate, EntityState.Modified); } } }
As you can see directly above, I have attempted to use context.ObjectStateManager.ChangeObjectState - is this correct ? Many thanks in advance for any help someone can provide, Graeme Edited by: user4487499 on -May- : Edited by: user4487499 on -May- : Edited by: user4487499 on -May- :
