Question

我有一个NServiceBus的问题，我首先得到NHibernate无法从NHibernate特定Bag映射的错误，当我把它作为IList时，我得到一条消息，NHibernate找不到这个IList的具体实现。我很难过。

这是我收到的第一个错误：

System.InvalidCastException: Unable to cast object of type
'NHibernate.Collection.Generic.PersistentGenericBag`1[CustomerDirect.Interfaces.Document.DocumentSubTemplate]'
to type

然后，当我将我的财产变为IList时，我得到了这个：

Answer 1

我使用NHibernate Loquacious映射使其工作。因为我们从不查询除了saga本身ID之外的Saga数据，所以我在nvarchar（max）字段中使用了Json这样的复杂属性。我用这个要点让它发挥作用：https://gist.github.com/phillip-haydon/1936188

NServiceBus中的NHibernate - IList <t>或List <t>
