数据库错误Windows服务器上部署asp.net应用程序2012

Question

我试图部署具有Enitity框架Windows的服务器上2012年我在服务器上安装了Visual Studio 2015年企业的asp.net应用程序。当我运行在Visual Studio只是正常的应用程序，它创建使用实体框架代码第一次在AppDbContext的构造函数的字符串的LocalDB。

我复制的解决方案C：/ inetputb/wwwroot文件和所使用的Internet信息服务管理器来创建一个新的网站，我把我的解决方案为物理路径的表示层。

当我开始浏览网页我得到这个错误：

我试图unsuccessfuly几个星期部署此项目，确实需要把它完成。有人可以告诉我该怎么做错了吗？ 这个我试图做使用SQL Server Express 2014无龙头安装Visual Studio中，仍然不能使它工作部署它之前..
