What are the .src files.
I saw it in the ibuyspy starter kit application.In the folder Source viewer.What are there use and there advantages.

In the page directive (@ Page) you can specify several things to change the way the page works when it's compiled.

1. Strait inline code. Plain ASPX file with a server script block in it.
   <%@ Page%>

2. Inherited source file class (runtime-compiled). ASPX file derives from a class that is compiled at runtime using a SRC file
   <%@ Page Inherits="MyClass" Src="MyClass.aspx.vb" %>

3. Inherited assembly class (Pre-compiled). ASPX file derives from a class that lives in a pre compiled assembly.
   <%@ Page Inherits="MyApplication.MyClass" %>


Note: the CodeBehind attribute of the page directive is not significant to ASP.NET, but to Visual Studio.
