我已经搞砸了我的迁移,我用于IgnoreChanges初始迁移,但现在我想要删除所有迁移,并开始使用所有逻辑进行初始迁移.

当我删除文件夹中的迁移并尝试Add-Migration它并不生成一个完整的文件(它是空的 - 因为我上次没有做任何更改,但现在已删除,迁移).

是否有任何Disable-Migrations命令,所以我可以重新运行Enable-Migrations？

我如何首先在实体框架代码中使用数据库视图,

我正在尝试将SQL视图映射到EF 5.0 Code First w/Migrations中的实体,以便在页面上显示一些基本信息,而无需查询多个表以获取该信息(目前需要大约20秒才能加载.不是很好.).我听说有可能这样做,但我无法弄清楚或在网上找到正确的方法.

这是我的观点:

CREATE VIEW [dbo].[ClientStatistics]
AS
SELECT       ROW_NUMBER() OVER (Order By c.ID) as Row, c.LegacyID, c.ID, c.ClientName, slc.AccountManager, slc.Network,
                             (SELECT        MAX(CreatedDate) AS Expr1
                               FROM            dbo.DataPeriods
                               WHERE        (ClientID = c.ID)) AS LastDataReceived,
                             (SELECT        MAX(ApprovedDate) AS Expr1
                               FROM            dbo.DataPeriods AS DataPeriods_2
                               WHERE        (ClientID = c.ID)) AS LastApproved,
