Midori was fascinating. Joe Duffy's writing on it is the most comprehensive I've seen: https://joeduffyblog.com/2015/11/03/blogging-about-midori/

I've heard someone at Microsoft describe it as a moonshot but also a retention project; IIRC it had a hundred plus engineers on it at one time, including a lot of very senior people.

Apparently a bunch of research from Midori made it into .NET so it wasn't all lost, but still...
