VS2015: Cannot use a namespace from another project

Question

I have two C# projects, one is a .NET Core Web (Project A) and the other a Windows Service project (project B).

I've added project A as a reference of B. Project B is the main one. For some reason, I can't see from B the namespace provided by the project A. The namespace is listed in B's References list. If I click on the listed reference I get this error:

What I've tried so far:

clean + rebuild
VS2015 restart
Machine reboot

I'm building against the same .NET Framework 4.6.1

In the configuration manager for the configuration you are building against are they both being built? — Mike Cheel, Aug 03 '17 at 14:35
Also check that both are using the same version of the .net framework. — Mike Cheel, Aug 03 '17 at 14:35
@MikeCheel both are built, yes. Also, I'm building against the same .NET Framework 4.6.1 — Gianluca Ghettini, Aug 03 '17 at 14:37
Is the platform target the same? Go through the Compile options and double check. — Mike Cheel, Aug 03 '17 at 14:40
I'm checking, in the meantime I've added some clarifications. Please have a look. Platform target for the .NET core is Debug-AnyCPU-IISExpress — Gianluca Ghettini, Aug 03 '17 at 14:43
agree with @MikeCheel this sounds like you are building the two projects for different .net versions — meJustAndrew, Aug 03 '17 at 14:43

Are you sure that this structure is actually correct? Generally a web specific project type is similar to an exe project (such as your service) in being at the "top" of referencing relationships, and not being used as a reference in other projects. — Damien_The_Unbeliever, Aug 03 '17 at 14:48
@Damien_The_Unbeliever not quite sure it's correct. Do you suggest to move the bulk of the .NET core project into it's own project, target a DLL and then have it referenced by both the .NET Web app project and the Windows Service? — Gianluca Ghettini, Aug 03 '17 at 14:50
Yes, I'd normally expect the shared code to be in some kind of class library project. — Damien_The_Unbeliever, Aug 03 '17 at 14:51
