namespace clientReport
{
    class Program
    {
        static void Main(string[] args)

            {
                string templateDocument = @"C:\Temp\ClientsTemplate.docx";
                string finalDocument = @"C:\Temp\ClientsReport.docx";

                ClientLst cl = new ClientLst();
                cl.Data = new List<ClientOutput>();

                var q = context.Clients.ToList<Client>();

                foreach (Client c in q)
                {
                    ClientOutput co = new ClientOutput();
                    co.Cid = c.C_ID;
                    co.Name = c.Name;

                Console.WriteLine("Count of records read ..." + cl.Data.Count.ToString());

                DocumentGenerator dg = new DocumentGenerator(cl);
                DocumentGenerationResult result = dg.GenerateDocument(templateDocument, finalDocument, SaveOptions.Pdf);

                Console.Write("Press any key to continue ...");
                Console.ReadKey();
            }
        }        
    }
