So I’m making the switch from PHP and going right back to basics with [ASP.NET](http://ASP.NET) (C#). I have a suitably hefty text book, but I’m failing at the first example. ```auto <%@ Page Language="C#" %> <%@ Import Namespace="System.Net.Mail" %> Send Mail
Email sent!
``` Simply trying to send an email, but I get a compilation error with: [FONT=Arial, Helvetica, Geneva, SunSans-Regular, sans-serif]\*The type or namespace name ‘Mail’ does not exist in the class or namespace ‘[System.Net](http://System.Net)’ (are you missing an assembly reference?) \*Any ideas? This seems so trivial. [/FONT]
