Microsoft takes ASP.NET MVC into the open with community patches and bug-fixes

ASP.NET MVC, Microsoft's Web application framework, has been open sourced since its first version, and was switched to Microsoft's permissive license in 2009. All in all, there's a difference between open development and mere open source. Before, the source was available, nevertheless its development was Microsoft's sole concern; third parties had no ability to suggest changes or contributions of their own, and little ability to comment on the work that Microsoft was doing.

This is the second project that Microsoft has operated in doing so. The Windows Azure SDK for the company's cloud computing service is as well an open project, hosted on github, that allows third-party contributions.
