如何自动连接到数据库

我有Visual Studio 2013, SQL Server 2014 Express，我无法在我的ASP中使用web.config连接到数据库。. NET MVC项目。

我的服务器名称是MySqlExpress。

我使用了这个连接字符串

<add name="Context"
     providerName="System.Data.SqlClient"
     connectionString="Data Source=.'MYSQLEXPRESS;AttachDbFileName=|DataDirectory|'test.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True" />

并尝试了其他一些，但仍然得到

错误50 -本地数据库运行时错误。无法找到LocalDB实例。服务器不可用或未找到

我自己设置服务器，集成安全。

我有一些其他的SQL服务器在我的机器上，但同样我不能通过web.config连接到他们，但我可以通过服务器资源管理器。

这是我的web.config，我使用实体框架+代码优先策略
