带有联接的 EF 4.1 ExecuteStoreQuery

Question

是否可以将具有连接结果的 ExecuteStoreQuery 映射到域对象？

即我们有 2 个域对象

public class Customer
{
    public virtual int Id { get; set; }
    public virtual string Name { get; set; }
    public virtual ICollection<Order> Orders { get; set; }
}

，

public class Order
{
    public virtual int Id { get; set; }
    public virtual string Description { get; set; }
    public virtual int CustomerId { get; set; }
    public virtual Customer Customer { get; set; }
}

现在如果我运行此查询：

 string query = "select * from Order as Order 
    inner join Customer as Customer on Order.CustomerId = Customer.Id 
    where freetext(Order.Description, 'something')";
_objectContext.ExecuteStoreQuery<Order>(query);

结果将是所有客户设置为空的订单集合。 我该如何解决这个问题？

谢谢你！
