Accessing Data Through Web Services

One of the ways that a Silverlight application can access data is through web services. These can be ASP.NET Web Services (ASMX), Windows Communication Foundation (WCF) services, or representational state transfer (REST) services. Here, you will concentrate on using a WCF service, which is the preferred way of accessing data in a Silverlight application through web services.

Try It Out: Accessing Data Through a WCF Service

To demonstrate accessing data from a WCF service, you will build the same application that you built in Chapter 5 to try out the DataGrid. (For more information about any part of this exercise regarding the DataGrid, refer back to Chapter 5.) The difference will be that the application will get the data through a web service.
