All that is strictly necessary to deploy most ASP.NET applications—to deploy most .NET applications—is to copy the new files to the proper directories on the proper machine, overwriting any previous versions of files if they exist. This is referred to as XCOPY deployment.
XCOPY deployment is so simple as to cause experienced developers to ask, “Is that all there is to it?” It provides all the deployment benefits of .NET except for the ability to deploy assemblies globally (i.e., to use application code modules for multiple applications) and to pre-compile the application. To implement globally available code modules, you will use global deployment, described later in this section. Pre-compilation scenarios of local deployment will be covered shortly.
XCOPY is a command-prompt command that originated in the DOS days and has been enhanced for use in modern networks. It is used to copy files and directories from one location to another. The basic syntax is:
XCOPY source destination switches

For a full list of the switches available, go to a command prompt and enter:
