Hi, I am new to Umbraco and I am in the process of migrating a some existing websites across.

I have some aspx.cs files handling contact form emails etc. and want to use these in Umbraco to save starting again with those features. I have set up a template for the contact form and I dropped the associated aspx.cs file (just sends an email with the contact form content) into the Umbraco templates folder. But I am getting this error (it works fine outside of Umbraco):

Server Error in '/' Application.

Compilation Error

Line 5:  using System.Web.UI.WebControls;
Line 6:  using System.Net.Mail;
Line 7:  public partial class SendMail : System.Web.UI.Page
Line 8:  {
Line 9:      protected void Btn_SendMail_Click(object sender, EventArgs e)

In my Master template I have this:

<%@ Master Language="C#" MasterPageFile="~/umbraco/masterpages/default.master" AutoEventWireup="true" %>

In my Contact Page template I have:

<%@ Master Language="C#" MasterPageFile="~/masterpages/Master.master" AutoEventWireup="true" CodeFile="SendMail.aspx.cs" Inherits="SendMail" %>

My aspx.cs file:

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Web.UI.WebControls;
using System.Net.Mail;
public partial class SendMail : System.Web.UI.Page
{
    protected void Btn_SendMail_Click(object sender, EventArgs e)
    {

..........................................................

Can I get this working as is in Umbraco or do I need to compile it and wrap in a Macro?

Many thanks if you can point me in the right direction?
