IsBodyHtml = true is undoubtedly the most important part.

But if you want to provide an email with both a text/plain part and a text/html part composed as alternates, it is also possible using the AlternateView class:

MailMessage msg = new MailMessage();
AlternateView plainView = AlternateView
     .CreateAlternateViewFromString("Some plaintext", Encoding.UTF8, "text/plain");
// We have something to show in real old mail clients.
msg.AlternateViews.Add(plainView); 
string htmlText = "The fancy part.";
AlternateView htmlView = 
     AlternateView.CreateAlternateViewFromString(htmlText, Encoding.UTF8, "text/html");
msg.AlternateViews.Add(htmlView); // And a html attachment to make sure.
msg.Body = htmlText;  // But the basis is the html body
msg.IsBodyHtml = true; // But the basis is the html body
