Why is my C# SMTP Email code failing in Visual Studio Code

I have a suspicion that the problem I am having has something to do with Visual Studio Code rather than with the C# code itself. I have recently configured my Visual Studio Code IDE to compile and build a C# (Command Line Console App) project and solution. But the moment I add meaningful code, it fales to properly recognize simple classes. Here is the simple test code I am trying:

using System;
using System.Net;
using System.Net.Mail;
using System.Net.WebSockets;

namespace SendEmailWIthGoogleSMTP
{
    class Program
    {
        string fromMail ="[email protected]";
        string password ="REDACTED";

        MailMessage message = new MailMessage();
        message.From = new MailAddress(fromMail);
        message.Subject = "Test Subjecting";
        message.To.Add(new MailAddress([email protected]);
        message.Body ="This is a test";
        message.IsBodyHtml= false;

    }
}

But here is the problem. It complains that ‘message’ is not defined albeit it does not complain after I define it. I know that sounds confusing, so here is the screen shot.
Please Help

    Your code causes an issue because the initialization of MailMessage and its properties occurs directly within the class scope, which is not allowed. Instead, this should be done within a method, like Main() or another function.
    Class-level statements in C# can only declare fields and methods.

    Your code contains several issues that prevent it from even compiling

    • Missing Main method
    • Line 17: [email protected] is not a string
    • Line 17: missing a closing )

    This compiles:

    using System;
using System.Net;
using System.Net.Mail;
using System.Net.WebSockets;

namespace SendEmailWithGoogleSMTP
{
  class Program
  {
    static void Main(string[] args)
    {
      string fromMail = "[email protected]";
      string password = "REDACTED";

      MailMessage message = new MailMessage();
      message.From = new MailAddress(fromMail);
      message.Subject = "Test Subjecting";
      message.To.Add(new MailAddress("[email protected]"));
      message.Body = "This is a test";
      message.IsBodyHtml = false;
    }
  }
}

    Your code looks like it has been written using top level statements but inside a class and should be:

    using System;
using System.Net;
using System.Net.Mail;
using System.Net.WebSockets;

string fromMail ="[email protected]";
string password ="REDACTED";

MailMessage message = new MailMessage();
message.From = new MailAddress(fromMail);
message.Subject = "Test Subjecting";
message.To.Add(new MailAddress([email protected]);
message.Body ="This is a test";
message.IsBodyHtml= false;

    It also looks like you’ve introduced a typo during redaction. The line below is missing double quotes around the email address and a closing parenthesis:

    message.To.Add(new MailAddress([email protected]);

    Should be:

    message.To.Add(new MailAddress("[email protected]"));
