From this post i came to know that there exist some platform improvements for implementing pinch and zoom functionality. By using this new method( ManipulationDeltaEventArgs.PinchManipulation ) how i can implement pinch to zoom functionality in windows phone.

Apart from this i need to implement scrolling feature too to the image control. In my current implementation, i am using Toolkit(gesture listener) for pinch and zoom functionality along with scroll viewer, now it seem both scrolling and and pinching events are overlapping and hence it produces a bad user experience.

Can anyone help me to solve this issue in my application. I am looking some code samples that help me to achieve the functionality.

I am not expected to get Multi touch behavior(codeplex) as answer. The assemblies using in the project are quite old and i heard that many of them are facing issues with marketplace submission only because of this.
