Microosft has updated Microsoft Surface 2.0 SDK and Runtime

Microsoft Surface 2.0 SDK and Runtime Update We have updated our SDK and runtime bits to include improved support for Windows Touch Enabled devices. There were some issues in the Microsoft Surface Input Stack handling of reports sent by a digitizer in serial mode. These issues caused the input stack to not report all touches reported by the digitizer reliably. The new build handles input from serial and parallel/hybrid digitizer more robustly. We encourage you to use this update, especially if you are building applications that will run on Windows 7 touch enabled PCs. With the Microsoft Surface 2.0 SDK, you can easily create applications to take advantage of the next generation Surface computing device. The applications you create can be adapted for other Windows 7 touch-enabled devices as well.

Development platform that delivers familiarity and innovation opportunity:
• Build upon Windows 7, NET 4.0 and WPF 4.0 and integrates with Visual Studio 2010
• Benefit from consistency in experience across Windows 7 devices with the Surface multi-touch controls.
• Develop multi-user, multi-touch and object interaction unique to Surface 2.0 - innovative experiences that excite users and customers.

Easy to use tools and resources you need:
• The Surface 2.0 SDK includes controls, API, samples, and documentation to create applications that take advantage of PixelSense. You can also use it to create touch applications for other Windows 7 touch devices.
• The Surface 2.0 SDK Microsoft Input Simulator allows you to develop and test on Windows 7 PCs (32 or 64-bit)

NOTE: This release replaces the Surface Toolkit for Windows Touch Beta
