C# 新ASP.NET MVC 4项目的例外情况

我已经创建了一个新的ASPXMVC4项目。我在默认的MVC4模板上创建了一些新文件。然而，现在，当我在系统中单击寄存器时，我得到一个异常。我没有在注册表中更改任何内容，只是添加了一些视图。我得到的异常如下所示。有人知道如何解决这个问题吗？ 非常感谢

我也有同样的问题。我通过启用并运行SQL Server服务解决了这个问题

对于我来说，我在Windows7机器上作为管理员做了以下工作 在“开始”菜单中：键入服务>按enter键>查找SQL Server（SQLExpress）>右键单击>单击属性>如果禁用启动类型，则切换到自动或手动>单击启动

希望如此
