Question

我正在使用SimpleMembership作为ASP.Net MVC 4应用程序。

连接字符串配置为在开发和生产中使用SQL Server而不是LocalDB。这很好，除了生产中没有App_Data文件夹，SimpleMembership尝试在应用程序池被回收后（第一次可重现）在第一个HTTP请求上访问App_Data。对于后续的HTTP请求，它不会尝试访问App_Data。

如果我预先创建App_Data并授予读/写权限，则不会引发错误。在App_Data中没有创建文件。

我是否可以配置（在生产中创建虚拟App_Data文件夹）以防止这种“虚拟”访问尝试？

堆栈跟踪供参考：

您应该将InitializeSimpleMembershipAttribute.cs中以“WebSecurity.InitializeDatabaseConnection（...）”开头的行复制到Global.asax中Application_Start方法的开头

protected void Application_Start()
{
    WebSecurity.InitializeDatabaseConnection("MyDBContext", "UserProfile", "UserId", "UserName", autoCreateTables: true);

    AreaRegistration.RegisterAllAreas();
    WebApiConfig.Register(GlobalConfiguration.Configuration);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
    AuthConfig.RegisterAuth(); 
}

SimpleMembership需要App_Data文件夹
