Saw a really nice article on using Reactive extensions with silverlight + wcf : http://abovetheblue.blogspot.com/2010/03/reactive-extensions-silverlight-and-wcf.html
Basically you need to use
Basically you need to use
- Observable.FromEvent
- Take(1) ... to automatically unsubscribe from the call.
- Now just make the standard WCF call.
i.e.:
public Page()
{
InitializeComponent();
CustomersServiceClient client =
new CustomersServiceClient();
IObservable<IEvent<GetCustomersCompletedEventArgs>> observable =
Observable.FromEvent<GetCustomersCompletedEventArgs>(
client, "GetCustomersCompleted"
).Take(1);
observable.Subscribe(
e =>
{
if (e.EventArgs.Error == null)
{
var customers = e.EventArgs.Result;
dg.ItemsSource = customers;
}
});
client.GetCustomersAsync();
}I can think up a nice clean code generator that will make WCF calls with neat error handling. Till then.
Enjoy!
