Midori (which means green in Japanese) was the code name for a managed code operating system (OS) being developed by Microsoft with joint effort of 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 in which the kernel, device drivers, and application software are all written in managed code. It was designed for concurrency, and could 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.
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.
