C# ASP.NET添加迁移在IdentityModels.cs更改时生成空迁移

我一直在对IdentityModels.cs进行一些更改。主要是忽略几个字段并将表从“AspNetUsers”重命名为“Users”。但是，在我保存这些更改、构建项目并生成迁移之后，它只是空的

我对IdentityModels.cs所做的更改如下：

public class ApplicationUser : IdentityUser
{
    public virtual List<Bestelling> Bestellingen { get; set; }

    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;
    }
}

然后呢

update-database

但是什么也没发生，因为迁移看起来是这样的：

namespace Eindopdracht.Migrations
{
using System;
using System.Data.Entity.Migrations;

public partial class databasev2 : DbMigration
{
    public override void Up()
    {
    }

    public override void Down()
    {
    }
}
}

现在，在其他车型中，我添加了以下内容：

public virtual DbSet<Klant> Klants { get; set; }

这似乎不是个好办法

解决方案是更改configuration.cs文件并在IdentityModels.cs中进行细微更改。感谢您的帮助

问题在您的

OnModelCreating

方法中

modelBuilder.Entity<IdentityUser>().

我已经像你说的那样做了更改，但是迁移仍然是空的。。我只需要在更改后构建，然后添加迁移，对吗？是的，没错。如果自上次生成迁移后数据库没有更改，则不会生成迁移。迁移是在Migrations目录中生成的，但它仍然是空的，就像之前的一样..请编辑您的问题并显示您的DbContext类？我想知道您的_MigrationHistory表是否一团糟-尝试为迁移指定一个不同的名称-
