Creating default.aspx.designer.cs file in ASP.NET

I need the file "default.aspx.designer.cs" which is not auto generating even for the first time when I am trying to create a ASP.NET web application using C#

Everyone says delete the default.aspx.designer.cs code and then click on "convert to web application" but I can neither find the file default.aspx.designer.cs nor the optio开发者_JS百科n "convert to web application"

How to auto generate a designer.cs file in Visual Studio 2005 using c# ASP.NET web application?

What do you need the designer file for? When I create asp .net, I only have the default.aspx and default.aspx.cs underneath that.
