带有新数据库的EF6生成'支持< Database>自创建数据库以来，上下文已经发生变化。 [英] EF6 with new database generates 'The model backing the <Database> context has changed since the database was created.'

问题描述

我已经通过迁移几周的时间开发了Code First数据库。我昨天添加了几张表，得到错误

I have been developing a Code First database via migrations for a couple of weeks. I added a few tables yesterday and got the error

The model backing the 'DanceDb' context has changed since the database was created.

在尝试了几件事后，我删除了数据库，删除了所有代码迁移，清理了解决方案一个迁移并运行一个更新数据库，但我仍然得到相同的错误。

After trying a couple of things I dropped the database, removed all code migrations, cleaned the solution, added a single migration and ran an Update-Database but I still get the same error.

如果我再次运行添加迁移，没有任何生成，所以有人认为它们是相同。

If I run Add-Migrations again, nothing is generated so something thinks they're the same.

我正在运行VS2013。我有两个项目，一个是实体，另一个是MVC项目。我已经阅读了关于将实体移动到主要项目中的内容，但如果我听到过这样的话，听起来像是向后的解决方案。

I'm running VS2013. I have two projects, one for the entities and the other for the MVC project. I've read about moving the entities into the main project but that sounds like a backwards solution if I've ever heard one.

这个运行再次？

推荐答案

一个工作是将数据库初始化程序设置为null

A work around is to set the database initializer to null

public class DanceDb : DbContext
{
    public DanceDb() : base("name=DanceEntities")
    {
        Database.SetInitializer<DanceDb>(null);
    }
}
