I just downloaded Aspose.Network Version 18.104.22.168 and I created a simple .Net 2.0 console app to email out a test message.
Here is the code snippet:
//Create the MailMessage Instance
MailMessage msg = new MailMessage("email@example.com","firstname.lastname@example.org","Test","hello, how are you?");
client = new SmtpClient("localhost");
catch (Exception ex)
When you don't specify a username in the SmtpClient object, then following error occurs:
Value cannot be null.
Parameter name: Username should not be null
This is a problem. Can you review this and see if it's a problem?
