Visual InterDev
A collection of elements that make up a Web site or distinct portion of a Web site organized under a virtual root. In Visual InterDev™, Web applications are built from Web projects.
A Web project can reference a single Web application. For example, you can have a Web site with two Web applications: one that defines an online catalog and one that defines pages for administrating the database for the catalog.
