Anatomy of an aspx page

Page Directive The page directive must be on the first line of an aspx page. It consists of Name/Value Pairs and sets parameters that will be used throughout the execution of the page ie. the language.

<%@ Page language="c#" debug="True" trace="False"%>

C# Code may be embedded in the page using script tags similar to javascript

<script language="c#" runat="server"> </script>

Notice the runat attribute is set to 'server'. This is what makes the code execute on the server rather than be parsed by the client.

Console applications start executing in the main method

<csharp>public static void Main() {}</csharp>

The .Net Framework can also execute on the web. Rather than having a Main method a web page starts it's execution with a method called Page_Load

<csharp>public Page_Load { }</csharp>

There are actually several method that are executed in an aspx page.
