[MVC] WebSecurity在VS2013中不识别

浏览数：43 / 时间：2015年06月09日

使用VS2013创建了MVC4项目以后，在filters中添加了类InitializeSimpleMembershipAttribute ，不能识别UserContext和WebSecurity，发现缺少WebMatrix.WebData的引用，在Nuget控制台中中运行：install-package Microsoft.AspNet.WebPages.Data即可添加，这样解决了WebSecurity的问题。对于UserContext，需要在model中添加一个AccountModel的类。

public class InitializeSimpleMembershipAttribute : ActionFilterAttribute
    {
        private static SimpleMembershipInitializer _initializer;
        private static object _initializerLock = new object();
        private static bool _isInitialized;

        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            // Ensure ASP.NET Simple Membership is initialized only once per app start

            LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);
        }

        private class SimpleMembershipInitializer
        {
            public SimpleMembershipInitializer()
            {
                Database.SetInitializer<UsersContext>(null);

                try
                {
                    using (var context = new UsersContext())
                    {
                        if (!context.Database.Exists())
                        {
                            // Create the SimpleMembership database without Entity Framework migration schema
                            ((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
                        }
                    }

                    WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
                }
                catch (Exception ex)
                {
                    throw new InvalidOperationException("The ASP.NET Simple Membership database could not be initialized.", ex);
                }
            }
        }
    }
