I am working on a ASP.net application and VS2008. We are being asked about compiling the application as a single dll file like VS2003 originally did. Apparently in VS2005 there were several improvements made and one of those was to compile to several dll files so parts of the web could be recompiled independantly. Is pre-compiling to a single dll an option in VS2008?

What is the difference between a Web Project and a Web Application?
Thanks
