This is the first release of Mono that includes the self-hosting Visual Basic environment. This is a preview of the Basic support, we will be releasing this officially at a later date.
The source code is available on a separate download (mono-basic package).
The environment includes Rolf Bjarne's Visual Basic 8 compiler written in Visual Basic 8, and Mainsoft's Visual Basic runtime for 2.0. The compiler only targets the 2.0 framework API, the runtime supports both 1.0 and 2.0 profiles. For more details, see http://www.mono-project.com/Main_Page
