How to Make a Website Application a DLL in ASP

1. Click 'Build > Publish [Project Name]' with your web application project open to open the 'Publish Web' dialog.
2. Select a target location by typing the location into the 'target location' text box, or by clicking the '...' button to browse to the location.
3. Select whether you want to include only the files necessary to run the application or if the publishing wizard should move all files from the application folder into the published directory.
4. Click 'Publish.' The single application DLL will be in the target location you specified along with all the supporting files necessary to run the application.
