Initial Installation (Service Broker)
SQL Server Service Broker is installed with the Database Engine. However, you must deploy Service Broker applications to use Service Broker functionality.
Installing the Database Engine
Service Broker is included in each instance of the Database Engine. By default, Service Broker is enabled in each instance, and in each new database.
To use Service Broker functionality, you deploy an application that is coded to use Service Broker messaging. If you do not have an existing application, you can design, code, and test a new application.
For more information about using Service Broker, see Overview (Service Broker).
