You don't need to publish anything to the development server. DS allows you
to run and debug ASP.NET applications without IIS. It runs directly from VS
or VWD and works directly off VS Web project. You don't even have to compile
or build the Web.

Web sites are different from client projects, nothing is installed on the
client. Hence 'ClickOnce' term does not apply directly to VWD.
