ASP.NET标识从AspNetUsers表中删除列

Question

当我使用ASP.NET Identity第一个代码方法时,我想以自己的方式在AspNetUsers表中生成列.我不需要存储多个具有空值的列.我只需要列Id,SecurityStamp和UserName.我发现只有帖子在这里:AspNet Identity 2.0电子邮件和用户名重复,但它仍然没有被发现(由于Santosh评论中的错误).

所以有人能告诉我如何解决这个问题吗？

编辑:甚至可以删除其中一些列/属性？

谢谢

实际上你可以忽略这些字段,只需要在上下文类中配置你的实体OnModelCreating:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
        base.OnModelCreating(modelBuilder);
        modelBuilder.Entity<IdentityUser>().Ignore(c => c.AccessFailedCount)
                                           .Ignore(c=> c.LockoutEnabled)
                                           .Ignore(c=>c.LockoutEndDateUtc)
                                           .Ignore(c=>c.Roles)
                                           .Ignore(c=>c.TwoFactorEnabled);//and so on...

        modelBuilder.Entity<IdentityUser>().ToTable("Users");//to change the name of table.

}

实际上,您可以在OnModelCreating上下文类中配置您的实体.

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity<IdentityUser>().Ignore(u => u.AccessFailedCount);
    //and so on...
}

或者,如果您的应用程序为每个配置都有一个单独的文件(我建议使用),您可以这样做:

public class ApplicationUserEntityTypeConfiguration : EntityTypeConfiguration<ApplicationUser>
{
    public ApplicationUserEntityTypeConfiguration()
    {
        Ignore(p => p.AccessFailedCount);
        //And so on..
    }
}

简短的回答是否定的，除非您自己实施。或者您可以等待他们在codeplex上开源 asp.net 身份。谁知道这需要多长时间。

默认实现包括所有未使用的列（见下文）。
