當WebAPI控制器執行時EntityFramework 6模型的更新沒有被反映

Question

我已經將數據庫視圖添加到SQL Server 2012.之後，我更新了我的EntityFramework（v6）模型，並構建並驗證了它。從ASP.Net WebAPI（v2）項目中刪除並添加了引用我的EntityFramework庫，以確保我引用了這個最新的更新。控制器具有到上下文和EF模型類的所有正確鏈接。

public IEnumerable<RTV_DedicationComments> Get(int EntryNum) 
    { 
     //var query = from c in context.RTV_GetAllDedicationsNames orderby c.DedicationName where c.DedicationName.StartsWith(Name) select c; 
     var query = context.RTV_DedicationComments 
          .Where(d => d.EntryNumber == EntryNum) 
          .OrderBy(d => d.EntryNumber) 
          .Select(d => d); 

     var results = query.ToList(); 

     return results; 
    } 

在運行時上設置InnerException返回以下錯誤：： {「無效的列名稱PlatEntryNumber'\ r \ n無法使用視圖或函數的引用我從這個GET方法所做的更新沒有錯誤由於綁定錯誤的「dbo.RTV_DedicationComments」「}當執行查詢：

var results = query.ToList(); 

‘PlatEntryNumber’是從數據庫和之前的更新EF模型UT它已被刪除，它不會顯示作爲控制器中的dbcontext的字段。

我打開SQL Server事件探查器，看看該查詢執行那裏，它做：

exec sp_executesql N'SELECT 
[Project1].[EntryNumber] AS [EntryNumber], 
[Project1].[CommentDate] AS [CommentDate], 
[Project1].[Comment] AS [Comment], 
[Project1].[CommentBy] AS [CommentBy] 
FROM (SELECT 
    [Extent1].[EntryNumber] AS [EntryNumber], 
    [Extent1].[CommentDate] AS [CommentDate], 
    [Extent1].[Comment] AS [Comment], 
    [Extent1].[CommentBy] AS [CommentBy] 
    FROM (SELECT 
[RTV_DedicationComments].[EntryNumber] AS [EntryNumber], 
[RTV_DedicationComments].[CommentDate] AS [CommentDate], 
[RTV_DedicationComments].[Comment] AS [Comment], 
[RTV_DedicationComments].[CommentBy] AS [CommentBy] 
FROM [dbo].[RTV_DedicationComments] AS [RTV_DedicationComments]) AS [Extent1] 
    WHERE ([Extent1].[EntryNumber] = @p__linq__0) AND (@p__linq__0 IS NOT NULL) 
) AS [Project1] 
ORDER BY [Project1].[EntryNumber] ASC',N'@p__linq__0 int',@p__linq__0=5943651 

還有什麼我可以檢查刪除的WebAPI和EF之間的這些數據庫對象引用的殘餘？

Answer 1

的問題是與我的WebAPI的web.config文件。有一個指向舊數據庫的標籤。這對我來說有些困惑，因爲我認爲EF處理了到數據庫的所有連接，因此不需要WebAPI擁有數據庫信息。它正在工作。
