At least it influenced async/await, TPL, .NET Native, Span<>, local refs, ref structs, blittable structs, and few other C# 7.x and 8.0 features.

Reading between the lines of some Joe Duffy posts, I think Midori was a victim of rise to power from WinDev after that whole Longhorn/Vista history, only to end with UWP slowly getting back all the .NET features that they decided to throw away on the initial version of WinRT.

Apparently post .NET Core 3.0 there will be some changes happening to .NET Native. It was briefly mentioned at Connect 2018, but they didn't wanted to precise what exactly.
