Today we are announcing the availability of the Windows Home Server SDK. (download below)
As I stated in my Channel 9 video interview in January, enabling developers to build on Windows Home Server is an important goal for us. We include all sorts of developers in our definition, including pros doing it to make a living, hobbyists doing it for others just for the gratification, and makers who just do it for themselves.
Our little set of APIs let you integrate your Add-in into the Home Server Console and interact with some of the elements behind the solutions we provide. But all the interesting work that great Windows Home Server Add-ins will do will be done using the standard "Windows API".
