Getting started with Media Center development with the Windows Vista February CTP
The Windows Vista February 2006 community technology preview (CTP) is now available, and with it comes a version of the Media Center SDK that contains tools and samples that you can use to get started developing Media Center add-ins using the new Media Center Presentation Layer and Media Center Markup Language.
You can check out these instructions that will walk you though the end to end process of downloading the Vista February CTP, the Media Center SDK February CTP, and installing and configuring both on your computer so you can start developing Media Center applications using this new technology.
Also, Charlie Owen posted some details and screenshots of the tools and samples that I encourage you to take a look at. Hopefully reading this will get you as excited as I am about the platform enhancements that will be available to developers in Media Center for Windows Vista.
