错误：System.Data.MetadataException: 无法加载指定的元数据资源。

将自动生成的App.Config中的数据库连接字符串中"换成单引号‘。...

这个是更改之前的：

代码

<add name="AuthorizeContainer" connectionString="metadata=res://*/Model.Authorize.csdl|res://*/Model.Authorize.ssdl|res://*/Model.Authorize.msl;provider=System.Data.SqlClient;provider connection string="Data Source=Server;Initial Catalog=EIPS;Persist Security Info=True;User ID=sa;Password=123;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />

这个是更改之后的：

代码

<add name="AuthorizeContainer" connectionString="metadata=res://*/Models.Authorize.csdl|res://*/Models.Authorize.ssdl|res://*/Models.Authorize.msl;provider=System.Data.SqlClient;provider connection string="Data Source=Server;Initial Catalog=EIPS;Persist Security Info=True;User ID=sa;Password=123;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />

就是“metadata=res://*/Models.Authorize.csdl|res://*/Models.Authorize.ssdl|res://*/Models.Authorize.msl;”

metadata：指明.csdl/.ssdl/.msl三个文件的路径
