Microsoft Offers WiX to Open-Source Community

A Microsoft employee, Rob Mensching, lobbied the company to release WiX, which is now the first project from the software developer to be released through the Common Public License scheme.

Linuxinsider: Microsoft this week released a portion of its source code through an open-source license, posting the code on SourceForge , an online source-code repository, in its most high-profile code disclosure ever.

Here is where you can get the codes, I think it's a clever move from Microsoft, but the funny part is it might have been leaked soon so they decided to leak it in a more innocent way.
