Thanks Adrian, Thomas. ActiveWin.com Exclusive. Microsoft has posted it's Beta 1 version of Microsoft J#.Net Version 7.0 Beta 1 for download, it hasn't been posted on Download Center yet and the file is dated October 11, so it is unclear if this is a leak or not. However, it is on Microsoft's public servers and it is available for download. Here are some of the details:
