MVC使用基架添加控制器出现的错误:无法检索XXX的元数据

环境 vs2012

框架 mvc3  

数据库  sqlservercompact4.0

出现的错误如下:

---------------------------
Microsoft Visual Studio
---------------------------
无法检索“MvcMusicStore.Models.Album”的元数据。Using the same DbCompiledModel to create contexts against different types of database servers is not supported. Instead, create a separate DbCompiledModel for each type of server being used.

I switched providerName="System.Data.SqlServerCe.4.0" with providerName="System.Data.SqlClient", and it created the Controller and Views.

OK, so switching to providerName="System.Data.SqlClient" will get the controller and the views built, but the site won't run. If after using the switch to build the controller, you then switch it back to providerName="System.Data.SqlServerCe.4.0", it will then run. It's not pretty, but it should get you through the tutorial. 

分为两部分

 第一就是把webconfig中的数据库配置   providerName="System.Data.SqlServerCe.4.0 修改成 providerName="System.Data.SqlClient"  这样就可以添加成功控制器了

第二 生成控制器以后 在把  providerName="System.Data.SqlClient  改回 providerName="System.Data.SqlServerCe.4.0   就OK了

没有第二部的话  也就是说不还原回去的话 会报如下错误:

[Win32Exception (0x80004005): 找不到网络路径。]

[SqlException (0x80131904): 在与 SQL Server 建立连接时出现与网络相关的或特定于实例的错误。未找到或无法访问服务器。请验证实例名称是否正确并且 SQL Server 已配置为允许远程连接。 (provider: Named Pipes Provider, error: 40 - 无法打开到 SQL Server 的连接)]
