Its in beta production but this is epitome of awesomeness. I am really looking forward to other developers to implement this in their upcoming applications, than people with resistive screen can also enjoy Multi-Touch =). check out the link below to download a neat little app to try this on your resistive screen phone.

Info:
In December last year, i posted an Alpha version of this SDK. Now it is mature enough to announce it as Beta. This SDK allows developers to build Dual-Touch enabled applications. so let’s get into action.
Features:
- Pinch to Zoom Support
- Drag (swipe) support.
- Replacement events for the mouse move fires only when a single finger detected.
- Multiple events based on gestures.
- Performance optimized, memory footprint is minimal.
To use this SDK you will need Visual Studio Professional or better. start a new Smart Device Project, and add the SDK to your references.
The SDK is consists of only one object, which is DualTouchSDK. We will need one instance of this class for every control that supports pinch to zoom or drag in your application.
There are several methods, properties and events that can be utilized in order to achieve multitouch effect. i have done my best to make this as easy as possible, my code is now complex but it is necessary to achieve easy implementation.
