Services in a project can be shared with others by adding them to the Service Library. To share a service, drag it from the project to a category in the Service Library. By default the Service Library provides categories to organize services by type as database, messaging, and web services. You can also add categories.
When you drag a service into the Service Library, a copy of the service is added to the library and stored in Directory Services. The original service is not affected when you modify the copy that has been stored in the Service Library. Changes to a service in the project are not reflected in the Service Library automatically.
