I noticed in some example files that the form.Designer code is embedded into the form's source code, rather than put as a shortcut of some sort inside the form (hard to explain, but I'm sure you know what I mean).

Is there an option I can enable in VS2005 that does this by default? I like having the Designer code in the form's code, simply because it's 1 less open file in the IDE. I looked around everywhere with no luck.

Is this just something that occured in previous versions of VS that they changed in 2005?
