On Monday, April 5, 2004, as part of the Shared Source Initiative, Microsoft releases the source code for the Windows Installer XML (WiX) developer tool to SourceForge under the IBM Common Public License or CPL. The WiX project is the first Shared Source Initiative to go "public" on Source Forge rather than a Microsoft site. It is also the first to use an externally created “Open Source” license.
Microsoft supports the idea that a software developer should be free to choose how they license their work and for the goals of WiX, the CPL was the right fit.
