将数据库添加到mvc3应用程序时出错

Question

当我将数据库添加到Visual Studio 2010以制作MVC3应用程序时，发现此错误。我使用SQL Server 2008的

The database 'C:\USERS\KAPIL.AGRAWAL\DOCUMENTS\VISUAL STUDIO 2010\PROJECTS\DT\DT\APP_DATA\DTRIAL.MDF' 
    cannot be opened because it is **version 661**. 
    This **server supports version 655** and earlier. A downgrade path is not supported. 
    **Could not open new database** 'C:\USERS\KAPIL.AGRAWAL\DOCUMENTS\VISUAL STUDIO 2010\PROJECTS\DT\DT\APP_DATA\DTRIAL.MDF'. 
    CREATE DATABASE is aborted. 
    An attempt to attach an auto-named database for file c:\users\kapil.agrawal\documents\visual studio 2010\Projects\dt\dt\App_Data\dtrial.mdf failed. 
    A database with the same name exists, or specified file cannot be opened, 
    or it is located on UNC share. 

Answer 1

看来，数据库与SQL Server 2008 R2（611版本）创建，您要使用SQL Server 2008 RTM或SP1（版本655）打开它。您不能从较高版本备份/恢复或分离/附加到较低版本。您可以将本地数据库服务器升级到SQL 2008 R2。有关更多信息，请参阅this article。
