How to compile VS2003-created webapp in VS2008 Release mode? (only Debug is available)

In VS2008SP1 (Team System, XP SP3 Pro rus) I open ASP.NET webapplication project created in VS2003 ( .csproj contains string
ProductVersion = "7.0.9466").
For ex, [1a]

VS2008SP1 forces the conversion of project.
Everythings seems to work.
But in Properties (or Property Pages, Configuration Manager or Configuration)
I find only Debug mode.

Though creating New ASP.NET webapp project or Website I have available
- Active (Debug)
- Debug
- Release

The problem is the same if I open old (apparently created in VS2003, [1a]) ASP.NET webapp as WSP (web site project), both from FileSystem (VSinternal webserver) or from LocalIIS or as WAP, i.e. from .csproj [1a].

So, the question is how to compile VS2003 webapplication in VS2008SP1 in Release mode?

What is determining in the code of website the outdated version of if I open webapplication as WSP,
i.e. without the use of VS project or solution files?

Also I'd like also to understand the differences between Active (Debug) and Debug

ASP.NET website's build bases on the debug attribute in web.config file.

You can use web deployment project to precompile ASP.NET application.

Who is marking my unanswered questions as resolved, I wonder?
