Asp.net Linq include（）适用于开发人员，但不适用于azure

我有一个数据库模式，如下所示：

FailureItem
---------------
FailureID int foreign key references Failure (FailureID)
DatabaseID int NULL foreign key references Items (DatabaseID)
FailureDescription varchar(200)

Item
---------------
DatabaseID int primary key identity(1,1)
ItemDescription varchar(200)

Dim items as List(Of FailureItems) =
    context.FailureItems.include("Item").where(function(x) x.FailureID = _failureID)



<asp:GridView ID="gv1" runat="server">
    <Columns>
        <asp:BoundField DataField="databaseID" Visible="false" />
        <asp:BoundField DataField="FailureDescription" headertext="Failure Description" />
        <asp:BoundField DataField="Item.ItemDescription" headertext="Item Description" />
    </Columns>
</asp:GridView>

我使用linq将其绑定到gridview，如下所示：

FailureItem
---------------
FailureID int foreign key references Failure (FailureID)
DatabaseID int NULL foreign key references Items (DatabaseID)
FailureDescription varchar(200)

Item
---------------
DatabaseID int primary key identity(1,1)
ItemDescription varchar(200)

Dim items as List(Of FailureItems) =
    context.FailureItems.include("Item").where(function(x) x.FailureID = _failureID)



<asp:GridView ID="gv1" runat="server">
    <Columns>
        <asp:BoundField DataField="databaseID" Visible="false" />
        <asp:BoundField DataField="FailureDescription" headertext="Failure Description" />
        <asp:BoundField DataField="Item.ItemDescription" headertext="Item Description" />
    </Columns>
</asp:GridView>

Dim项作为列表（故障项的列表）=
context.FailureItems.include（“项”）。其中（函数（x）x.FailureID=\u FailureID）

这在我的开发机器上非常有效。当我将其发布到azure上时，我收到错误“在所选数据源上找不到名为'Item.itemsdescription'的字段或属性”。我做错了什么？

我最终将代码更改为以下代码，这起到了作用：

Dim items =
    (from fi in context.FailureItems
     where(fi.FailureID = _failureID)
     select new with {
         fi.databaseID,
         fi.FailureDescription,
         ItemDescription = If(fi.Item isnot nothing, fi.Item.ItemDescription, nothing)
     }).ToList

您确定正在使用正确的连接字符串吗？在角色的属性窗格中进行检查，确保服务配置设置设置设置为“云”，并验证所有设置是否正确。我检查了所有设置，但仍然无法工作-我甚至登录到实例并检查了连接字符串。
