IoC, UnitOfWork with Ninject and Entity Framework

我试图为我的服务类实现一个通用存储库。但是当我尝试在 Web 层中绑定我的 DbConext 时，我需要引用实体框架。

我的DbContext

  public partial class SalesDbContext : DbContext, IUnitOfWork
    {
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        }
        public DbSet<Activity> Activities { get; set; }
        /// <summary>
        /// Allows saving changes via the IUnitOfWork interface.
        /// </summary>
        void IUnitOfWork.Commit()
        {
            base.SaveChanges();
        } 

我的IUnitOfWork

public interface IUnitOfWork
{
    /// <summary>
    /// Saves changes to all objects that have changed within the unit of work.
    /// </summary>
    void Commit();
}

我的Repository

public class Repository
{
    protected IUnitOfWork UnitOfWork { get; set; }
    protected SalesDbContext Context
    {
        get { return (SalesDbContext)this.UnitOfWork; }
    }
    public Repository(IUnitOfWork unitOfWork)
    {
        if (unitOfWork == null) throw new ArgumentNullException("unitOfWork");
        this.UnitOfWork = unitOfWork;
    }
    private DbSet<TEntity> GetDbSet<TEntity>() where TEntity : class
    {
        return this.Context.Set<TEntity>();
    }
    protected IEnumerable<TEntity> GetAll<TEntity>() where TEntity : class
    {
        return this.GetDbSet<TEntity>()
            .AsEnumerable();
    }
    protected virtual void SetEntityState(object entity, EntityState entityState)
    {
        this.Context.Entry(entity).State = entityState;
    }
}

最后我的Ninject配置

private static void RegisterServices(IKernel kernel)
{
    IUnitOfWork unitOfWork = new SalesDbContext();
    kernel.Bind<IUnitOfWork>().ToConstant(unitOfWork);
    kernel.Bind<IMarketService>().To<MarketService>();
} 

问题是 Ninject 想要对实体框架的引用，但我不想在这里添加它，它属于数据层。

你认为 DbContext 的 ToConstant 实现会导致问题吗？
