As Steve Clayton points out, the list of official sessions at PDC (October 27-30th) was recently updated with four Windows 7 sessions on graphics, touch computing, energy efficiency and new native networking APIs for Web services.
Windows 7: Graphics Advances
Windows 7 enables you to advance the graphics capabilities of your applications while carrying forward existing investments in your Win32 codebase, including GDI and GDI+. New enhancements to DirectX let Win32 applications harness the latest innovations in GPUs and LCD displays, including support for scalable, high-performance, 2D and 3D graphics, text, and images. Also learn how to leverage the GPU's parallelism for general-purpose computation such as image processing.
Windows 7: Optimizing for Energy Efficiency and Battery Life
A single application can reduce mobile battery life by up to 30%. Windows 7 provides advances for building energy-efficient applications. In this session we will discuss how to leverage new Windows infrastructure to reduce application power consumption and efficiently schedule background tasks and services.
Windows 7: Touch Computing
In Windows 7, innovative touch and gesture support will enable more direct and natural interaction in your applications. This session will highlight the new multi-touch gesture APIs and explain how you can leverage them in your applications.
Windows 7: Web Services in Native Code
Windows 7 introduces a new networking API with support for building SOAP based web services in native code. This session will discuss the programming model, interoperability aspects with other implementations of WS-* protocols and demonstrate various services and applications built using this API.
