Using VS2005 from early betas on I found the problem that new "File System Webs" are always some kind of a directory.
This means the web is allways addressed by http://my.domain/TheWebIMade
Sounds not so bad, but in reality I mostly build root webs like http://ttncf.pp-p.com
I was in the hope this problem will change till release - it did not [:(]
So what happens if you try to build a root web with VS2005.
You can partial cheat the system by adding your own call to the developer webserver in the Tolls menu.
With this (and the right setting in the properties of your web app) you can run and debug your site.
But you loose:
Images in design - if they are addressed absolute.
Drag support for images - they will addres "wrong".
Drag support for links - the same.
So what you get is a "per theory" design view - but without images.
If you do not need to drag those images - you can place them (if possible) on the destination web and use the whole path as address

And there (mean beta) were a lot of entries in the NGs - no solution for this common task
