每一個現在，實體框架超時在asp.net

Question

那麼實體框架Timesout上總是相同的SQL視圖，然後我總是有兩種選擇固定的網站

我運行此查詢

USE [ibeems] 
DBCC FREEPROCCACHE 

OR

我改變視圖

然後網頁在接下來的幾天立即打開。

這是視圖

USE [ibeems] 

GO 
ALTER VIEW [dbo].[ViewNewVerificationList] 
AS 
    SELECT   
     dbo.Quotation.ClientId, dbo.Quotation.ActualTurnover,  
     dbo.Quotation.VerificationFee, dbo.Quotation.ConsultationFee,

一些技巧

1. 使用SCHEMABINDING
2. Index the views

您也可以remove a single plan from SQL Server，或可能也許創建一個存儲過程，並與EF映射。
