Microsoft Robotics Developer Studio & RCX Support? What is the last version of the Microsoft Robotics Developer Studio that supports the RCX?

The Wikipedia link (http://en.wikipedia.org/wiki/Microsoft_Robotics_Developer_Studio) indicates RCX was dropped in the "latest" version but doesn't indicate what version.
I'm not an expert on Robotics Developer Studio, but the phrase indicating that support was dropped in the latest version was added in July 2008, so you'll need to go back to version 1.5 in order to have RCX support.
