Entity Framework 不在现有数据库上创建标识表

Question

我当前的项目有两个数据库连接：

第一个用于 IdentityModel 并使用本地 .mdf 文件。第二个我在外部 SQL 服务器上创建并首先使用数据库导入。

现在我想在外部 sql 服务器上创建 IdentityModel 表，因此只使用一个连接/数据库。我更改了 ApplicationDbContext 以匹配 web.config.

中的外部连接名称

ApplicationDbContext

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("SAMPLEEntities", throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

Web.config

<add name="SAMPLEEntities" connectionString="metadata=res://*/Models.modelone.csdl|res://*/Models.modelone.ssdl|res://*/Models.modelone.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=thedatabase;initial catalog=SAMPLE;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

现在我认为会生成表格，但事实并非如此。当我尝试在程序包管理器控制台中进行手动更新时，出现以下错误：

不支持创建 DbModelBuilder 或从使用数据库优先或模型优先创建的 DbContext 写入 EDMX。 EDMX 只能从不使用现有 DbCompiledModel 创建的代码优先 DbContext 中获取。

我还尝试将本地 .mdf 文件导入 sql 服务器，这样我就可以复制表格，但是 mdf 文件是由 VS 2015 创建的，不会加载到 SQL 服务器2012.

关于如何在外部 SQL 服务器中生成/添加表的任何建议？

找到答案，

第 1 步。使用以下 SQL 脚本在外部 sql 服务器上创建表：

/****** Object:  Table [dbo].[__MigrationHistory]    Script Date: 5/15/2014 3:57:55 PM ******/
SET ANSI_NULLS ON

 CONSTRAINT [PK_dbo.__MigrationHistory] PRIMARY KEY CLUSTERED

GO

ALTER TABLE [dbo].[AspNetUserRoles] CHECK CONSTRAINT [FK_dbo.AspNetUserRoles_dbo.AspNetUsers_UserId]
GO

第 2 步：更改身份模型的 web.config 连接以匹配以下内容（不要重复使用或更改 edmx 连接）

<add name="IdentityDbContext" connectionString="Data Source=MYSERVER;Initial Catalog=MYDATABASE;Integrated Security=True;" providerName="System.Data.SqlClient" />

第 3 步：在 IdentityModel.cs

中设置连接

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("IdentityDbContext", throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}
