【问题描述】：
我正在尝试为身份验证创建自定义表，但无论我尝试重新创建身份表多少次，我都会收到此错误：
实体类型“BBRoleType”和“UserRoleType”不能共享表“UserRoleTypes”，因为它们不在同一类型层次结构中，或者它们之间没有有效的一对一外键关系和匹配的主键。
这是我在数据库中的用户表：
并导出为 SQL：

创建表后，我为数据库添加了一个 ADO.NET 数据实体模型。
我创建了这些类以映射到自定义标识类：
public class BBUserLogin : IdentityUserLogin<Guid> { }
public class BBUserRole : IdentityUserRole<Guid> { }
public class BBRoleType : IdentityRole<Guid,BBUserRole> { }
public class BBUserClaim : IdentityUserClaim<Guid> { }
public class BBUser : IdentityUser<Guid, BBUserLogin, BBUserRole, BBUserClaim>
{
public DateTime CreateDate { get; set; }
public DateTime LastOnlineDate { get; set; }
public DateTime? BirthDate { get; set; }
public string FacebookAccessToken { get; set; }
public string FacebookName { get; set; }
public string FacebookId { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<BBUser, Guid> manager)
{
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
userIdentity.AddClaim(new Claim(TCCustomClaimTypes.FirstName, this.FacebookName.SubstringUpToFirst(' ')));
return userIdentity;
}
}
然后将我的 DbContext 设置为：
public class ApplicationDbContext : IdentityDbContext<BBUser, BBRoleType, Guid, BBUserLogin, BBUserRole, BBUserClaim>
{
public ApplicationDbContext() : base("MyIdentityConnection")
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.HasDefaultSchema("dbo");
modelBuilder.Entity<BBUser>().ToTable("User");
modelBuilder.Entity<BBUserClaim>().ToTable("UserClaim");
modelBuilder.Entity<BBUserLogin>().ToTable("UserLogin");
modelBuilder.Entity<BBUserRole>().ToTable("UserRole");
modelBuilder.Entity<BBRoleType>().ToTable("UserRoleType");
modelBuilder.Entity<BBUser>().Property(x => x.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
modelBuilder.Entity<BBUserClaim>().Property(x => x.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
modelBuilder.Entity<BBRoleType>().Property(x => x.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
}
我认为我并不重要，但我尽可能使用 Guid/[uniqueidentifier] 作为 ID（使用通用 TKey 的地方）。 IdentityUserClaim 不允许更改 Id 类型，因此我为此使用 bigint。并不是说我认为这很重要:-)
我整天都在为这个问题撞墙，但我不知道我做错了什么。
