Huh? Ok I always wanted to create those misleading article headings you find in magazines and newspapers… But this is a first too; Microsoft has extended its Shared Source Initiative to post a project completely on SourceForge under the [CPL] (Nooo, not GPL). The actual project is the Windows Installer XML (WiX), a set of command line tools that enable developers/ISVs to create MSI packages during their build process. It is a toolset that is used internally to build the setups of products like SQL, BizTqlk, Exchange, Office, etc.) So go and check this thing out! <http://sourceforge.net/projects/wix/>

Interesting. MS releasing software on SF.net. could be a start to something interesting.
