'''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]].

== History ==
The code name ''Midori'' was first discovered through the [[PowerPoint]] presentation ''CHESS: A systematic testing tool for concurrent software''.<ref>{{cite report |last1=Musuvathi |first1=Madanlal |last2=Qadeer |first2=Shaz |last3=Ball |first3=Thomas |date=November 2007 |url=http://research.microsoft.com/apps/pubs/default.aspx?id=70509 |title=CHESS: A systematic testing tool for concurrent software |publisher=Microsoft |access-date=2008-07-22}}</ref>

Another reference to Midori was found in a presentation shown during the ''Object-Oriented Programming, Systems, Languages & Applications'' ([[OOPSLA]]) October 2012 conference,<ref>{{cite news |last=Foley |first=Mary Jo |date=November 8, 2012 |url=https://www.zdnet.com/article/microsofts-midori-operating-system-skunkworks-project-soldiers-on/ |title=Microsoft's Midori operating-system skunkworks project soldiers on |website=[[ZDnet]] |publisher=[[CBS Interactive]] |access-date=2012-11-08}}</ref> and a paper<ref>{{cite conference |last1=Gordon |first1=Colin |last2=Parkinson |first2=Matthew |last3=Parsons |first3=Jared |last4=Bromfield |first4=Aleks |last5=Duffy |first5=Joe |date=October 2012 |url=https://dl.acm.org/doi/pdf/10.1145/2384616.2384619 |title=Uniqueness and Reference Immutability for Safe Parallelism |publisher=Association for Computing Machinery |book-title=Proceedings of the ACM International Conference on Object Oriented Programming Systems Languages and Applications |pages=21–40 |location=Tucson, Arizona, USA |doi=10.1145/2384616.2384619 |conference=OOPSLA '12|citeseerx=10.1.1.365.5541 }}</ref> from the conference's proceedings.
