It is a path to enlightenment with multiple stops. :)

Start with Joe Duffy blog posts about Midori architecture.

Then hop on to his talks.

"Safe Systems Programming in C# and .NET"

"RustConf 2017 - Closing Keynote: Safe Systems Software and the Future of Computing by Joe Duffy"

Then you can watch "Inside .NET Native" from Channel 9

Finally there are the specs and related discussions that lead up to C# 7.3 design.

The TL;DR; version, basically async/await, the UWP AOT compiler, improved handling of value types, spans (aka slices), improved GC (TryStartNoGCRegion()) have their roots in System C# used in Midori.

Also there are some influences of Singularity, namely Bartok and MDIL, on the WP 8.x AOT compiler, but that is not longer relevant.

Ah, so you meant the standard innovations that came out of Midori. I thought you were talking about some new abstraction I hadn't heard of called "outcomes". ¯\_(ツ)_/¯

I either missed or forgot about this stuff, gives me a nice rabbit hole to go down, thanks.
