Answer 1

Tested following code and works for me:

        // STEP 1: Navigate to this page https://www.google.com/settings/security/lesssecureapps & set to "Turn On"

        var message = new MimeMessage();
        message.From.Add(new MailboxAddress("Joey Tribbiani", "YOU_FROM_ADDRESS@gmail.com"));
        message.To.Add(new MailboxAddress("Mrs. Chanandler Bong", "YOU_TO_ADDRESS@gmail.com"));
        message.Subject = "How you doin'?";

        message.Body = new TextPart("plain")
        {
            Text = @"Hey Chandler,I just wanted to let you know that Monica and I were going to go play some paintball, you in?-- Joey"
        };

        using (var client = new SmtpClient())
        {
            client.Connect("smtp.gmail.com", 587);


            // Note: since we don't have an OAuth2 token, disable
            // the XOAUTH2 authentication mechanism.
            client.AuthenticationMechanisms.Remove("XOAUTH2");

            // Note: only needed if the SMTP server requires authentication
            client.Authenticate("YOUR_GMAIL_NAME", "YOUR_PASSWORD");

            client.Send(message);
            client.Disconnect(true);
        }
