.NET Core Entity Framework Fluent api error, DateTime properties have text as column type

In my model namespace, I have different model classes. I have DateTime fields in my different classes. When I run

dotnet ef migrations add InitialCreate 

without problem, it adds a migration and I am able to update the database too.

When I looked up my initialCommit.Designer.cs, I saw that all of my DateTime properties have column type text.

Like this:

namespace myapp.API.Models
{
    public class User
    {
        public int Id { get; set; }
        public string UserName { get; set; }
        public string Gender { get; set; }
        public DateTime BirthDate { get; set; }
        public string KnownAs { get; set; }
        public DateTime CreatedOn { get; set; }
        public DateTime LastActive { get; set; }
        ..
    }
}

namespace myapp.API.Models
{
    public class Photo
    {
        public int Id { get; set; }
        public string Url { get; set; }
        public string Description { get; set; }
        public DateTime DateAdded { get; set; }
        public bool IsMain { get; set; }
        public string PublicId  { get; set; }
        public User User { get; set; }
        public int UserId { get; set; }
    }
}

namespace myapp.API.Migrations
{
    [DbContext(typeof(DataContext))]
    [Migration("20200206201625_initialCommit")]
    partial class initialCommit
    {
        protected override void BuildTargetModel(ModelBuilder modelBuilder)
        {

                {
                    b.Property<int>("Id")
                        .ValueGeneratedOnAdd()
                        .HasColumnType("INTEGER");

                    b.ToTable("Users");
                });

            modelBuilder.Entity("myapp.API.Models.Value", b =>

            modelBuilder.Entity("myapp.API.Models.Photo", b =>

                    b.HasOne("myapp.API.Models.User", "User")
                        .WithMany("Photos")
                        .HasForeignKey("UserId")
                        .OnDelete(DeleteBehavior.Cascade)
                        .IsRequired();
                });

        }
    }
}

As you can see, all of my DateTime fields are defined like this :

b.Property<DateTime>("DateAdded").HasColumnType("TEXT");
