Silverlight 4 Data and Services Cookbook

Persisting data using a standardized service

In the previous recipe, we connected with the service and read out the result of the service call. However, we can also send data back to the service as a type known by the service. If a type is used as the type for a parameter or as the return type for a service method, that type will be exposed by the service as well.
