title: Windows Phone 8 Callback WCF Service
body: <p>I have a Windows Phone 8 Application and a WCF Service that implements Callback model. I'm having trouble configuring the service reference. I've tested the service using wsDualHttpBinding for a Windows Form Application Client instead the WP8 App, and it worked perfectly. However, this binding is not suitable for WP8 Apps and I have to change configuration. Can someone suggest me a simple working configuration for the service that works with my WP8 Application?</p>
