✅ How To Improve my code

namespace E.Commerce.Persistence.Data.DataSeed

    public class DataInitializer
    {
        private readonly ApplicationDbContext DbContext;
        public DataInitializer(ApplicationDbContext dbContext)

            await DbContext.SaveChangesAsync();
        }

        private async Task SeedData<T, TKey>(string fileName) where T : BaseEntity<TKey>
        {
            JsonSerializerOptions options = new JsonSerializerOptions
            {
                PropertyNameCaseInsensitive = true
            };

            if (!await DbContext.Set<T>().AnyAsync())
            {
                var path = Path.Combine(
                                        Directory.GetCurrentDirectory(),
                                        "Data",
                                        "DataSeed",

                if (!File.Exists(path)) throw new FileNotFoundException($"Seed file not found: {path}");
                var data = await File.ReadAllTextAsync(path);
                var list = JsonSerializer.Deserialize<List<T>>(data, options);

                if (list?.Count > 0)
                {
                    await DbContext.Set<T>().AddRangeAsync(list);
              }}
        }  }
}
