Bill Gates just kicked off the Office Developer Conference with an announcement and a demo of the March 2006 CTP of VSTO “V3”. Office 2007 Beta 1 customers can download the VSTO V3 CTP by starting from Betaplace or by going to the Visual Studio Futures page.

Please note that the CTP works only with the Office 2007 Beta 1 Technical Refresh that Office released earlier this month.

Additional resources:

• The downloads details page takes you right to the download bits
• The CTP download package contains an extensive “ReadMe” whitepaper (you can see it after extracting the contents of the package)
• The whitepaper also links to an additional downloadable tutorial document

Have fun!
