c# - ASP.NET登录控件连接字符串错误: Keyword not supported: 'metadata'

Question

到目前为止，我一直在正常连接下工作，一切都很顺利 但是现在我已经切换到数据实体模型并使用新的连接字符串，我遇到了这个错误...我如何保留我的实体字符串以进行数据操作并仅将常规连接字符串用于登录控制？

连接字符串

<connectionStrings>
    <add name="LoginDB" connectionString="Data Source=****;Initial Catalog=int422_113b16;User ID=****;Password=****" />
    <add name="BlogEntities" connectionString="metadata=res://*/App_Code.BlogModel.csdl|res://*/App_Code.BlogModel.ssdl|res://*/App_Code.BlogModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source****;initial catalog=int422_113b16;user id=****;password=****;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
</connectionStrings>

找到答案... 刚理性思考了一下，查看了config文件 我所要做的就是更改提供者标记的 connectionStringName
