ASP.NET Identity 修改表名和主键类型

    public class UserLogin : IdentityUserLogin<Guid>
    {
    }

    public class UserRole : IdentityUserRole<Guid>
    {
    }

    public class UserClaim : IdentityUserClaim<Guid>
    {
    }

    public class Role : IdentityRole<Guid, UserRole>
    {
    }

    public class User : IdentityUser<Guid, UserLogin, UserRole, UserClaim>
    {
    }

public class XYZDbContext : IdentityDbContext<User, Role, Guid, UserLogin, UserRole, UserClaim>
    {
        /// <summary>
        /// 构造函数
        /// </summary>
        public XYZDbContext ()
            : base("XYZDbContext ")
        {
        }

        /// <summary>
        /// 在模型创建时
        /// </summary>
        /// <param name="modelBuilder">模型构建器</param>
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

            // 配置实体类型映射到的表名
            modelBuilder.Entity<User>().ToTable("User");
            modelBuilder.Entity<Role>().ToTable("Role");
            modelBuilder.Entity<UserLogin>().ToTable("UserLogin");
            modelBuilder.Entity<UserClaim>().ToTable("UserClaim");
            modelBuilder.Entity<UserRole>().ToTable("UserRole");
        }
    }
