How do I force myProject Choose .NetStandard assembly instead of TargetFramework

Today , There are Asp.Net (System.Web.HttpContext) and Asp.Net Core (Microsoft.AspNetCore.Http.HttpContext) in .net Framework , and there are a few packages use .net Framwork with System.Web.HttpContext and .net Core (.net standard) with Microsoft.AspNetCore.Http.HttpContext for sharing source , so when I use Asp.Net Core on .Net Framework , I just can not use that package because that package fouce me to use System.Web.HttpContext , but there is an available assembly in that package, How do I choose that ?

suggest to add 2 attributes on <PackageReference />

• TargFramework choose which dll file to reference
• Source restore from specified souce of Nuget.Config

I Have the same problem here, I Have a net472 app that requires to be full framework, and I consume a nuget (netStandard2.0), this nuget have a reference for another nuget that provides both net45 and netstandard2.0. Now I’m stuck at using the net45 version cause I can’t control how the targetframework will be choosed. This would not be a problem using packages.config because I could just add a reference to this dependency and choose the targetframework for netstandard2.0 but now using PackageReference this is not possible.

This is definitely PackageReference bug or removed feature (that should have being disclaimed).
