how to set default namespace in VS 2005 web project?

[Bob]

I'm a few hours into VS 2005 beta and it looks pretty good. I was able to
follow the MSDN article about ASP.NET 2.0 master page and created a couple
of pages based on a master page. Now I realized that the code behind C#
files don't have a namespace statement, which I can manually add, but where
is the setting for the default namespace for the entire project? Well, a
web project is no longer called a project, it's just a Web Site, and
therefore no more project file. I think the feature to set a default
namespace for an entire project or web site is still there but I just can't
find it. Could anyone help?

Thanks
Bob
