MS-SQL communication in dotnet core under linux throwing errors

Im running on the default port 1433. when I execute a simple query against the DB all works well. but when I try to run a stored procedure .. like this:

DataTable result = null;

SqlCommand command = new SqlCommand();
command.CommandType = System.Data.CommandType.StoredProcedure;
command.CommandText = procedureNameWithDbVersionPrefix;
command.CommandTimeout = m_nTimeout;
foreach (string item in m_Parameters.Keys)
{
    command.Parameters.Add(new SqlParameter(item, m_Parameters[item]));
}
string sConn = GetConnectionString();
using (SqlConnection con = new SqlConnection(sConn))
{
    try
    {
        con.Open();
        command.Connection = con;

        SqlQueryInfo queryInfo = Utils.GetSqlDataMonitor(command);
        using (KMonitor km = new KMonitor(KLogMonitor.Events.eEvent.EVENT_DATABASE, null, null, null, null) { Database = queryInfo.Database, QueryType = queryInfo.QueryType, Table = queryInfo.Table, IsWritable = (m_bIsWritable || Utils.UseWritable).ToString() })
        {
            using (SqlDataReader reader = command.ExecuteReader())
            {
                if (reader.HasRows)
                {
                    result = new DataTable();
                    result.Load(reader);
                }
            }
        }

        con.Close();
    }
    catch (Exception ex)
    {
        string sMes = "While running : '" + procedureNameWithDbVersionPrefix + "'\r\n Exception occurred: " + ex.Message;
        log.Error(sMes, ex);
        return null;
    }
}

I'm getting this exception only on Linux system. running on windows all works well.. actually event running inside a Linux based docker on windows all works well .. :\
