Midori is the code name for a managed code operating system being developed by Microsoft with joint effort of Microsoft Research. It has been reported[1][2] to be a possible commercial implementation of the Singularity operating system, a research project started in 2003 to build a highly dependable operating system in which the kernel, device drivers, and applications are all written in managed code. It was designed for concurrency, and can run a program spread across multiple nodes at once.[3] It also features a security model that sandboxes applications for increased security.[4] Microsoft has mapped out several possible migration paths from Windows to Midori.[5]


The code name Midori was first discovered through the PowerPoint presentation CHESS: A systematic testing tool for concurrent software.[6]

A new reference to Midori was found in a presentation shown during the OOPSLA 2012 conference in October 2012.[7]
