Ninject应该为UnitOfWork模式使用什么选项?

我在mvc项目中实现工作单元模式，

public class UnitOfWork : IUnitOfWork
{
    private TransactionScope _transaction;
    private readonly BodoShopEntities _db;
    public UnitOfWork()
    {
        _db = new BodoShopEntities();
    }
    public void Dispose()
    {
        if (_db != null)
        {
            _db.Dispose();
        }
        System.GC.SuppressFinalize(this);
    }
    public void StartTransaction()
    {
        _transaction = new TransactionScope();
    }
    public void Commit()
    {
        _db.SaveChanges();
        _transaction.Complete();
    }
    public DbContext Db
    {
        get { return _db; }
    }
}

也是repository pattern，

public partial interface IRepository<T> where T : class
{
    T GetById(object id);
    void Insert(T entity);
    void Update(T entity);
    void Delete(T entity);
    IQueryable<T> Table { get; }
    T Single(object primaryKey);
    T SingleOrDefault(object primaryKey);
    bool Exists(object primaryKey);
    IUnitOfWork UnitOfWork { get; }
}

在Ninject中，我使用InThreadScope作为工作单元，这是正确的吗?

private static void RegisterServices(IKernel kernel)
{
        kernel.Bind(typeof(IUnitOfWork)).To(typeof(UnitOfWork)).InThreadScope();
}
