afaik, almost all of Microsofr.AspNetCore.* assemblies will live within
Microsoft.NET.Sdk.Web
, unfortunately theMicrosoft.Extensions.*
packages still live as separate nuget.
that's normal
Msft.Extensions.*
were always separated from Msft.AspNetCore.*
because they are "USED" by AspNetCore but are not part of it :
DependencyInjection / Logging / Configurations / Options are good examples.
See how they are targeting netstandard2.0
you can use it in your old stack like Owin
/ Xamarin
... (kinda great for Logging / Options)
I'm still seeing app the Microsoft.AspNetCore packages on nuget are 2.2
