如何使用linq-to-nhibernate查询继承的类？

Question

假设我有课程Animal,Cat并且Dog.Cat并Dog继承自Animal.考虑以下代码:

var query = from animal in session.Linq<Animal>()
            where 
            animal.Color == "White"
            select animal;

如何向上述查询添加条件以查询实体类型？比如像animal.Type == typeof(Cat).

新提供商支持此功能:

var query = from animal in session.Query<Animal>()
            where animal.Color == "White" &&
                  animal is Cat
            select animal;
