本文介绍了解决Entity Framework CodeFirst在运行时检测到模型已更改的问题。通过在Global.asax文件中设置Database.SetInitializer<StuInfoDBContext>(null);可以避免程序尝试自动更新数据库结构。

异常：

Additional information: The model backing the 'StuInfoDBContext' context has changed since the database was created. Consider using Code First Migrations to update the database

解决办法：

Global.asax文件中加：Database.SetInitializer<StuInfoDBContext>(null);

using System.Data.Entity;
using Iweb.Areas.SiteInfo.Models;

namespace Iweb
{
    // Note: For instructions on enabling IIS6 or IIS7 classic mode, 
    // visit http://go.microsoft.com/?LinkId=9394801
    public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            
            Database.SetInitializer<StuInfoDBContext>(null);
            AreaRegistration.RegisterAllAreas();

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
        }
    }
}
