Making a simple SELECT in Asp.Net C#

I see, but there is a deeper issue with this. Let me explain, I made a MVC Asp.net C# app, I made the connection with salesforce but I need to show information [In this case taken from any module {Account}]. I got the customer id, secret serial number but the SELECT did not work. 
 

class Program
    {
        /// <summary>
        /// Strings connection for salesforce
        /// </summary>

        private static string _clientid = "Client123456789IDClient123456789IDClient123456789ID";
        private static string _clientSecret = "123456789123456";
        #region Username/passoword
        private static string _username = "myEmail@force.com";
        private static string _securityToken = "123456789123456";
        private static string _password = "myPassword" + _securityToken;
        #endregion
        private static string Agent = "salesforce-SDK-demo";
        private static string tokenRequest = "https://login.salesforce.com/services/oauth2/token";
    
        static void Main(string[] args)
        {
            var auth = new Salesforce.Common.AuthenticationClient();
            try {
                auth.UsernamePasswordAsync(_clientid, _clientSecret, _username, _password).Wait();
            }
            catch(Exception e)
            {
                Console.WriteLine(e.ToString());
            }
            
            var client = new ForceClient(auth.InstanceUrl, auth.AccessToken, auth.ApiVersion);
            Task<QueryResult<dynamic>> results = client.QueryAllAsync<dynamic>("SELECT id, FirstName, LastName, Email FROM Contact");
            results.Wait();
            var contacts = results.Result.Records;
            foreach (var contact in contacts)
            {
                Console.WriteLine(contact.FirstName);
            }

            Console.WriteLine("Press a key!");
            Console.Read();

        }
    }

This is what I did. When I debug it simply shows nothing. What am I doing wrong? 
Please help me with this. 
Thank you James.
