Add to Silverlight project service reference with non async generate operations

Question

Hey, I try to consume WCF service in Silverlight project but in ass Reference dialog windows i can't unchecked "Generate asynchronous operations" :/ Why I can't use non asynchronous in SL? When I add service reference to Console App I can unchecked it.

I need non asynchronous, cause in Console consume works ok, but in SL app I have error when use asynchronous methods :/

Please help ! :)

You can't use synchronous operations because such operations rely on the underlying APIs such as HttpWebRequest to also support synchronous operations. Silverlight versions of these only have asynchronous versions hence everything else has to by asynchronous as well.
