Introducing .NET 4.0: with Visual Studio 2010

9.2. Querying WCF Data Services

WCF Data Services uses the URL to pass query parameters. For example, to retrieve the film entities, add /Films to the end of the existing URL (for example, http://localhost/Chapter9/MovieService.svc/Films).

You should then be returned a list of all the films in AtomPub format (Figure 9-8).

Figure 9.8. Returning all the films from the database

Having all the data returned at once isn't too useful, so WDS supports a number of query operators that all work with the URL.

I have listed some commonly used methods in Table 9-1, but for a full list, please refer to http://msdn.microsoft.com/en-us/library/cc907912.aspx ...
