The topics contained in this section are intended to give you quick exposure to the UA SDK programming experience. Working through this tutorial gives you an introductory understanding of the steps required to create UA server and client applications. A sever is a construct that exposes endpoints, each of which exposes services according to the UA Service Model. The endpoint of a service specifies an address where the service can be found, a binding that contains the information that a client must communicate with the service, and a contract that defines the functionality provided by the service to its clients.
