The ProfileUri Property specifies the protocol used to access the resource.

The EndpointUrls Property specifies the URLs that the Server uses to access the resource.

The ServiceStatus Property indicates the result of the last attempt to communicate with the resource. The following common error values are defined:

ServiceStatus
