The samples from the book "Professional Microsoft Robotics Developer Studio" have been updated to work with RDS 4 Beta and are available for download from CodePlex:http://promrds.codeplex.com
There were very few changes required, but new users will find it more convenient to download the updated samples. Note that the projects in the updated samples are for Visual Studio 2010 because RDS no longer supports Visual Studio 2008. Also you must be on Windows 7 to use a Kinect sensor because the Kinect for Windows SDK requires Windows 7. The RDS 4 Beta currently requires that you install Kinect for Windows even if you only want to use the simulated Kinect. This requirement will be removed in the final release.
The samples will be updated again for the final release of RDS 4.
