Asp.net mvc 4 在MVC Web Api中使用EntitySetController扩展集合

asp.net-mvc-4 asp.net-web-api odata

Asp.net mvc 4 在MVC Web Api中使用EntitySetController扩展集合,asp.net-mvc-4,asp.net-web-api,odata,linq-to-nhibernate,Asp.net Mvc 4,Asp.net Web Api,Odata,Linq To Nhibernate,我正在使用OData框架（版本5.0.0）和MVC Web Api（MVC版本4.0.305060），无法使$expand查询用于我的集合 根据“支持的场景”下更具体的案例2，我应该能够扩展集合以在单个查询中包含它们的数据，但我的$expand查询似乎完全被忽略了。没有错误，响应完全相同，就像我完全忽略了$expand一样 这是我的数据结构（部分）： DebtCalculation - string Name - string Description - Collecti

我正在使用OData框架（版本5.0.0）和MVC Web Api（MVC版本4.0.305060），无法使$expand查询用于我的集合

根据“支持的场景”下更具体的案例2，我应该能够扩展集合以在单个查询中包含它们的数据，但我的$expand查询似乎完全被忽略了。没有错误，响应完全相同，就像我完全忽略了$expand一样

这是我的数据结构（部分）：

DebtCalculation
    - string Name
    - string Description
    - Collection<Expense> Expenses
    - Collection<Participant> Participants

Participant
    - bool HasPaid
    - User User
    - DebtCalculation DebtCalculation

Expense
    - decimal Amount
    - User Payer
    - Collection<Debtor> Debtors
    - DebtCalculation DebtCalculation

债务计算的元数据如下所示：


    <EntityType Name="DebtCalculation">
            <Key>
                    <PropertyRef Name="Id"/>
            </Key>
            <Property Name="Id" Type="Edm.Int64" Nullable="false"/>
            <Property Name="Name" Type="Edm.String"/>
            <Property Name="Description" Type="Edm.String"/>
            <NavigationProperty Name="Participants" Relationship="Sujut.Core.Sujut_Core_DebtCalculation_Participants_Sujut_Core_Participant_ParticipantsPartner" ToRole="Participants" FromRole="ParticipantsPartner"/>
            <NavigationProperty Name="Expenses" Relationship="Sujut.Core.Sujut_Core_DebtCalculation_Expenses_Sujut_Core_Expense_ExpensesPartner" ToRole="Expenses" FromRole="ExpensesPartner"/>
    </EntityType>






认识到任何问题吗

编辑：

问题似乎是将ODataController查询与Linq到NHibernate相结合。这是堆栈跟踪。升级到NH4.0.0.1000 alpha版本并没有解决问题。似乎是关于同一个问题
