我正在开发ASP。. NET MVC4应用程序与实体框架5,我使用模型第一模式。
但是,如果使用设计器生成的连接字符串,则简单成员关系将抛出以下错误:
......
InnerException: System.InvalidOperationException

设计器生成的连接字符串(不起作用):
<add name="STD" connectionString="metadata=res://*/Models.STD.csdl|res://*/Models.STD.ssdl|res://*/Models.STD.msl;provider=System.Data.SqlClient;provider connection string="data source=.SQLEXPRESS;initial catalog=STD;integrated security=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
连接字符串我手动添加(将工作):
<add name="STD" providerName="System.Data.SqlClient" connectionString="Data Source=.SQLEXPRESS;Initial Catalog=STD;Integrated Security=True;MultipleActiveResultSets=True" />
是的,simplemmembership只适用于SQL Server连接字符串,所以你需要在你的web.config中加入这样一个条目。不理想,但它像你说的那样工作…
这可能是你的答案:使用EF模型优先的simplememmembership
Jon Galloway的文章是一个很好的关于simplememmembership的信息资源,如果你还没有看到它:http://weblogs.asp.net/jgalloway/archive/2012/08/29/simplemembership-membership-providers-universal-providers-and-the-new-asp-net-4-5-web-forms-and-asp-net-mvc-4-templates.aspx
