send json data to controller doesn´t work in local sql express db

I have a CRUD view developed in asp.net core.

I´ve got a very simple model

public class Categoria
    {
        [Required]
        public string id { get; set; }

    }

I´ve got this for delete in my controller:

[HttpPost, ActionName("Delete")]
        public bool Delete(string jsonData)
        {
            Categoria categoria = (Categoria)JsonConvert.DeserializeObject(jsonData, typeof(Categoria));

            if (ModelState.IsValid)
            {
                _context.Categorias.Remove(categoria);
                _context.SaveChanges();

                return true;
            }
            else
            {
                return false;
            }
        }

As you can see i receive the parameters in the jsondata string. I expected to receive in my case a id string.

When i receive strings with no spaces it Works perfectly.

When i receive strings with spaces it Works when i work against a real sql-server, but it doesn´t Works when i work with a local sql express db.

For example if i try to delete this : "Hello Darling". In the jsondata string parameter i receive "HelloDarling" when i work against the local db instead of receiving the correct string "Hello Darling".

Tx in advanced.
