这是模型优先的方法。我已经对此进行了广泛的研究,但没有提出答案。我已经尝试了以下链接中的所有建议:
这似乎是同样的问题,但没有解决 实体类型 <classname> 不是当前上下文模型的一部分
这些是我已经研究过的链接,所以请不要回答为 ---- EF 4.1 Code First 错误的重复 - 实体类型 SomeType 不是当前上下文 的模型的一部分实体类型不是模型的一部分, 英法 5
这是 EDMX(为简洁起见):

单元测试代码:
<TestMethod()> _
Public Sub WorkOrderServiceTests_TestConnectivityThruService5()
Dim woService As New DatabaseContext
Dim woHeaders = New Repository(Of WorkOrderHeader)(woService)
Dim woTests = New Repository(Of WorkOrderTest)(woService)
Dim coHeaders = New Repository(Of CompanyHeader)(woService)
Assert.IsTrue(woHeaders.Count <> 0)
End Sub
我试图解决这个问题的事情:
1) 检查数据库 - 两个查询都正确返回数据。从 vwWorkOrderHeader 中选择 * 从 vwCompanyHeader 中选择 *
2) 从 EDMX 中删除 WorkOrderHeader 然后从数据库中重新创建它。
3) MOQed 了 DBContext 以确保它不是服务查询在做一些有趣的事情。这正确地返回了对象,因此这意味着它是上下文级别或更低级别的东西。
4) 逐步完成这两个测试,以确保它们使用相同的构建上下文的方法 - Thy do。
4) 逐步完成这两个测试,以确保它们使用相同的方法来构建存储库 - 你这样做。
5)唯一的区别是在DatabaseContext的以下功能期间:
Public Overloads Function [Set](Of T As Class)() As System.Data.Entity.IDbSet(Of T) Implements Interfaces.IDatabaseContext.Set
Return MyBase.Set(Of T)()
End Function
WorkOrderHeader 代码在 MyBase.Set(Of T)() 的手表中具有以下内容
{System.Data.Entity.DbSet(Of Insight.Model.WorkOrderHeader)} System.Data.Entity.DbSet(Of Insight.Model.WorkOrderHeader)
CompanyHeader 代码在 MyBase.Set(Of T)() 的手表中具有以下内容
{SELECT [Extent1].[Name] AS [Name], [Extent1].[Active] AS [Active], [Extent1].[Creator] AS [Creator], [Extent1].[Created] AS [Created], [Extent1].[Modifier] AS [Modifier], [Extent1].[Modified] AS [Modified], [Extent1].[ID] AS [ID] FROM (SELECT [vwCompanyHeader].[ID] AS [ID], [vwCompanyHeader].[Name] AS [Name], [vwCompanyHeader].[Active] AS [Active], [vwCompanyHeader].[Creator] AS [Creator], [vwCompanyHeader].[Created] AS [Created], [vwCompanyHeader].[Modifier] AS [Modifier], [vwCompanyHeader].[Modified] AS [Modified] FROM [dbo].[vwCompanyHeader] AS [vwCompanyHeader]) AS [Extent1]} System.Data.Entity.DbSet(Of Insight.Model.CompanyHeader)
我对此完全不知所措,并且正在进入解决同一问题的第三天。我希望对这个问题有一些新的看法可能会看到我犯的错误,或者指出我没有想到的测试问题的方向。
更新:
我删除了服务代码以确保它在 DBContext 中。我已将服务从等式中分离出来,以便仅使用存储库并且它们都使用相同的 DatabaseContext,因此它与连接字符串无关。我验证了模型浏览器中 Insight_Model/EntityContainer:Insight_Entities/Entity Sets/WorkOrderHeaders 下存在,并且 Insight_Model/Entity Types/WorkOrderHeader 下存在。似乎 DatabaseContext 甚至没有尝试查询实体集的概念模型。
