Midori (operating system)

Midori (which means green in Japanese) was the code name for a managed code operating system (OS) being jointly developed by Microsoft and Microsoft Research. It had been reported^[2][3] to be a possible commercial implementation of the OS Singularity, a research project begun in 2003 to build a highly dependable OS whose kernel, device drivers, and application software would all be written in managed code. It was designed for concurrency, and would run a program spread across multiple nodes at once.^[4] It also featured a security model that sandboxes applications for increased security.^[5] Microsoft had mapped out several possible migration paths from Windows to Midori.^[6] Midori was discontinued some time in 2015, though many of its concepts were used in other Microsoft projects.

History

The code name Midori was first discovered through the PowerPoint presentation CHESS: A systematic testing tool for concurrent software.^[7]

Another reference to Midori was found in a presentation shown during the Object-Oriented Programming, Systems, Languages & Applications (OOPSLA) October 2012 conference,^[8] and a paper^[9] from the conference's proceedings.
