entity-framework - エンティティタイプ現在のコンテキストのモデルの一部ではありません

Question

これはモデルの最初のアプローチです。私はすでにこれを徹底的に研究していて、答えを思い付いていません。私は次のリンクですべての提案を試しました：

これは同じ問題のようですが、解決策がありません エンティティタイプ<classname>は、現在のコンテキストのモデルの一部ではありません

これらは私がすでに調査したリンクなので、重複して答えないでください---- EF4.1コードファーストエラー-エンティティタイプSomeTypeは現在のコンテキスト のモデルの一部ではありませんエンティティタイプはモデルの一部ではありません、EF 5

    Dim coHeaders = New Repository(Of CompanyHeader)(woService)
    Assert.IsTrue(woHeaders.Count <> 0)
End Sub

私が問題を解決しようとしたこと：

1）チェックされたデータベース-両方のクエリがデータを正しく返します。select * from vwWorkOrderHeader select * from vwCompanyHeader

2）EDMXからWorkOrderHeaderを削除してから、データベースから再作成しました。

3）DBContextをMOQして、サービスクエリが何かおかしなことをしていないことを確認しました。これはオブジェクトを正しく返すので、コンテキストレベル以下のものであることを意味します。

4）両方のテストをステップスルーして、コンテキストを構築するための同じ方法を使用していることを確認します-あなたはそうします。

4）両方のテストを実行して、リポジトリを構築するのと同じ方法を使用していることを確認します。

5）唯一の違いは、DatabaseContextの次の関数の間です。

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コードには、MyBase.Set（Of T）（）のウォッチに次のものがあります。

{System.Data.Entity.DbSet(Of Insight.Model.WorkOrderHeader)} System.Data.Entity.DbSet(Of Insight.Model.WorkOrderHeader)

CompanyHeaderコードには、MyBase.Set（Of T）（）のウォッチに次のものがあります。

{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)

私はこれについて完全に途方に暮れていて、同じ問題に取り組む3日目に入ります。問題を新たに見たときに、自分が犯したエラーが表示されたり、思いもよらなかった問題をテストする方向に向けられたりすることを期待しています。

アップデート：

サービスコードを削除して、DBContextにあることを確認しました。リポジトリのみが使用され、それらがすべて同じDatabaseContextを使用するように、方程式からサービスを分離しました。したがって、接続文字列に関連するものはありません。モデルブラウザのInsight_Model/EntityContainer：Insight_Entities / Entity Sets / WorkOrderHeadersの下に存在し、Insight_Model / Entity Types/WorkOrderHeaderの下に存在することを確認しました。DatabaseContextは、エンティティセットの概念モデルを照会しようとしていないように見えます。
