Question

我有一个现有的DB上下文，到目前为止，EF配置效果很好，如下所示

   protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

            // Configure Code First to ignore PluralizingTableName convention 
            // If you keep this convention then the generated tables will have pluralized names. 
            modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
            modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
            modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();
            modelBuilder.Conventions.Remove<StoreGeneratedIdentityKeyConvention>();
}

我跟着MSDN article扩展了MVC提供的Identity模型，以链接到我现有数据库上下文中的某个人。

App用户

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;
}

public virtual Person LinkedPerson { get; set; }//My reference to existing person definition

}

上下文

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

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

        public DbSet<Person> People { get; set; }

    }

只要我不使用注册或登录功能，该应用就可以正常工作。然而，一旦我注册为用户，我的所有模型现在都是重复的，一个是单数，另一个是复数形式。

在哪里可以告诉MVC身份框架不要重新创建多个表并使用现有的（Singular）数据库对象？

Answer 1

modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();对身份表不起作用。所以需要明确解决：

 protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        // Configure Code First to ignore PluralizingTableName convention 
        // If you keep this convention then the generated tables will have pluralized names. 
        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
        modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();
        modelBuilder.Conventions.Remove<StoreGeneratedIdentityKeyConvention>();

        modelBuilder.Entity<IdentityRole>().ToTable("AspNetRole");             
        modelBuilder.Entity<IdentityUserRole>().ToTable("AspNetUserRole");
        modelBuilder.Entity<IdentityUserLogin>().ToTable("AspNetUserLogin");
        modelBuilder.Entity<IdentityUserClaim>().ToTable("AspNetUserClaim");
        modelBuilder.Entity<ApplicationUser>().ToTable("AspNetUser");

    }

Identity DB上下文/提示没有复数表
