Microsoft released the Windows Installer XML (WiX) toolset yesterday under an open source license, though this is nothing crazy new since the company has released Rotor and even Windows source under its Shared Source program.

Still, this is the first code Microsoft has released under an OSS-approved license. It feels really weird to see something by Microsoft up on SourceForge.

But then again, after seeing Steve Balmer and Scott McNealy cracking jokes up on stage together last week, nothing surprises me anymore.
