SqlDataAdapter is missing from ASP.NET Core project

I am trying to get a database connection without Entity Framework using ADO.NET in a .NET Core 1.0 project.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using ASP_NETCore3.Models;
using System.Data;
using System.Data.SqlClient;
//using System.Configuration;

namespace ASP_NETCore3.Repository
{
    public class LineasRepository
    {
        private SqlConnection con;

        private void connection()
        {
            //TODO: Implementar variables de confuracion obtiendolas desde appsettings.json
            string constr = "Data Source=mylocaldb\\sql08;Initial Catalog=empresas;User id=user;Password=secret;Integrated Security=SSPI;";
            con = new SqlConnection(constr);
        }

        public List<LineasModel> GetAllLineas()
        {
            connection();
            List<LineasModel> LineasList = new List<LineasModel>();
            SqlCommand com = new SqlCommand("select * from CATLIN", con);
            com.CommandType = CommandType.Text;
            SqlDataAdapter da = new SqlDataAdapter(com);
            DataTable dt = new DataTable();
            con.Open();
            da.Fill(dt);
            con.Close();

            LineasList = (from DataRow dr in dt.Rows

                       select new LineasModel()
                       {
                           cod_lin = Convert.ToInt32(dr["COD_LIN"]),
                           nom_lin = Convert.ToString(dr["NOM_LIM"]),
                           margen = Convert.ToString(dr["MARGEN"]),
                       }).ToList();


            return EmpList;
        }
    }
}

      

        
        
        
      

    

As you can see, I can use System.Data.SqlClient, but for some reason the compiler says the SqlDataAdapter is missing.

What can I do? Can I install other packages from NuGet?
