问题：提供程序未返回ProviderManifestToken字符串。 [英] Issue : The provider did not return a ProviderManifestToken string.

问题描述

您好，



我正在通过指导Asp.net教程创建MVC应用程序MvcMovies（http://www.asp.net/mvc/tutorials/getting-started -with-aspnet-mvc3 / cs / access-your-model'-data-from-a-controller [ ^ ]）


当我使用具有读/写操作和视图实体框架的模板控制器添加新控制器时，我收到以下错误

Hello,

I am Creating MVC Application MvcMovies by guiding Asp.net tutorial(http://www.asp.net/mvc/tutorials/getting-started-with-aspnet-mvc3/cs/accessing-your-model''s-data-from-a-controller[^])

When I am adding new controller using template Controller with read/write actions and views entity framework, I am getting below error

"Unable to retrieve metadata for ''MvcTest2.Models.Movie''. The provider did not return a ProviderManifestToken string."

我的连接字符串是

My connection string is

connectionString="Data Source=.\\SQLExpress;Integrated Security=true;User Instance=true;AttachDBFilename=|DataDirectory|Movies.mdf;Initial Catalog=Movies"
providerName="System.Data.SqlClient"

也会出现错误

also get error in

connectionString="Data Source=|DataDirectory|Movies.mdf;"
providerName="System.Data.SqlClient"

教程中提到的内容。
