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

Question

I need the file "default.aspx.designer.cs" which is not automatically generated even the first time I try to create an ASP.NET web application using C #

Everyone says that delete the default.aspx.designer.cs code and then click "convert to web application", but I can not find the default.aspx.designer.cs file or the option "convert to web application"

How to automatically create designer.cs file in Visual Studio 2005 using a C # ASP.NET web application?

What is a designer file for? When I create asp.net, I have only default.aspx and default.aspx.cs.
