How can I temporarily solve this problem in EF Core 3.0? >_<

            builder.Entity<AppUser>(b =>
            {
                b.ToTable("AbpUsers"); //Sharing the same table "AbpUsers" with the IdentityUser
                b.ConfigureByConvention();
                b.ConfigureAbpUser();
                b.HasOne<IdentityUser>().WithOne().HasForeignKey<AppUser>(e => e.Id);

                //Moved customization to a method so we can share it with the Abp102MigrationsDbContext class
                b.ConfigureCustomUserProperties();
            });

Unhandled exception. System.InvalidOperationException: 'AppUser.CreationTime' and 'IdentityUser.CreationTime' are both mapped to column 'CreationTime' in 'AbpUsers' but are confi
gured with different nullability.

@gdlcf88 You can try making IdentityUser.CreationTime optional
