Sample : Music Store

In This Topic

Summary
This sample shows how a to use the generated code to implement a simple request response (client/server) application.

Details
The Request represents a search request for an album (like the interfaces exposed by Amazon or Play).
The response represents the result of the search, in this case either a set of results or an error. If results are returned then this may contain 0-n products (a product being an album), each album has one or more tracks, and a track has a title and length.
