为什么会出现此错误？

我需要更改IdentityRole和IdentityUser。

 public class ApkEntities : IdentityDbContext<ApplicationUser>
    {
        public ApkEntities ()
            : base("ApkEntities")
        {
        }

        public virtual void Commit()
        {
            base.SaveChanges();
        }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.Conventions.Remove<IncludeMetadataConvention>();
            modelBuilder.Configurations.Add(new AspNetRoleConfiguration());
            modelBuilder.Configurations.Add(new AspNetUserConfiguration());
        }
    }



 public class AspNetRoleConfiguration : EntityTypeConfiguration<ApplicationRole>
    {
        public AspNetRoleConfiguration(string schema = "dbo")
        {
            ToTable(schema + ".AspNetRoles");
            HasKey(x => x.Id);
            Property(x => x.Id).HasColumnName("Id").IsRequired().HasMaxLength(128).HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);
            Property(x => x.Name).HasColumnName("Name").IsRequired().HasMaxLength(256);
            Property(x => x.NameFa).HasColumnName("NameFa").IsRequired().HasMaxLength(50);
            Property(x => x.Description).HasColumnName("Description").IsOptional().HasMaxLength(250);
            Property(x => x.IsActivated).HasColumnName("IsActivated").IsRequired();
        }
    }

 public class AspNetUserConfiguration : EntityTypeConfiguration<ApplicationUser>
    {
        public AspNetUserConfiguration(string schema = "dbo")
        {
            ToTable(schema + ".AspNetUsers");
            HasKey(x => x.Id);
            Property(x => x.Id).HasColumnName("Id").IsRequired().HasMaxLength(128).HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);
            Property(x => x.Email).HasColumnName("Email").IsOptional().HasMaxLength(256);
            Property(x => x.PhoneNumberConfirmed).HasColumnName("PhoneNumberConfirmed").IsOptional();
            Property(x => x.FirstName).HasColumnName("FirstName").IsOptional();
            Property(x => x.LastName).HasColumnName("LastName").IsOptional();
            Property(x => x.DateCreated).HasColumnName("DateCreated").IsRequired();
            Property(x => x.PasswordHash).HasColumnName("PasswordHash").IsOptional();
            Property(x => x.SecurityStamp).HasColumnName("SecurityStamp").IsOptional();
            Property(x => x.UserName).HasColumnName("UserName").IsRequired().HasMaxLength(256);
        }
    }



     public class ApplicationRole : IdentityRole
        {
            public string Description { get; set; }
            public string NameFa { get; set; }
            public bool IsActivated { get; set; }
        }

     public class ApplicationUser : IdentityUser
        {
            public ApplicationUser()
            {
                DateCreated = DateTime.Now;
                LF_FavoraiteTeam = new Collection<LF_FavoraiteTeam>();
            }
            public string FirstName { get; set; }
            public string LastName { get; set; }
            public DateTime DateCreated { get; set; }
            public DateTime? LastLoginTime { get; set; }
            public bool? IsActivated { get; set; }
            public virtual ICollection<LF_FavoraiteTeam> LF_FavoraiteTeam { get; set; }

}

Answer 1

尝试在ApkEntities上下文中显式定义ApplicationUser和ApplicationRole DbSets，并删除IdentityRole和IdentityUser对象中已有的属性。已经通过继承IdentityDbContext来定义。

EntitySet＆＃39; AspNetRoles＆＃39;使用架构＆＃d;＆＃39;和表＃AspNetRoles＆＃39;已经定义了。每个EntitySet必须引用唯一的模式和表
