Visual Studio - Unresolved references from portable library in ASP.NET Core App

[gopokyo-colinn]

Hi there. I am having a bit of difficulty find the cause for the following issue.

I have an ASP.NET Core project that has a reference to a PCL library project. The project compiles and runs fine, but VS has reports unresolved references to all namespaces/classes in the PCL library. It worked at some point, and then just broke and I am not sure why.

ASP.NET Core project.json `{ "userSecretsId": "aspnet-MedicalJournals.API-b87b6ab9-7adb-4fac-8c87-5889aa14b375",

Same problem in .Net Core console project.

I'm glad I'm not alone. I'm just not sure what the standard is anymore :)

@balachir, can you see if you can repro?

I'm having the same problem. I have a PCL, an empty ASP.net core website which references said PCL and a .netcore library that references that same PCL. Both core projects fail at resolving them on VS but runs just fine.

it might be important to note I'm using Resharper, but the resolve problems doesn't go away even if I suspend Resharper.

part of the problem is that "Microsoft.NETCore.UniversalWindowsPlatform": "5.2.0" is delisted due to a metapackage not containing everything that was required. there was a published work around, but there are other issues involved that the UWP isn't the only affect type of project all asp.net core apps that are RTM have this issue. I have the problem only on my mobile dev box. Which makes this even more exacerbating since I can't do jack till it's resolved.

The application pub system will kick out the publication as a failure due this if you attempt to publish
