ApplicationUser namespace issue

The problem arises from trying to move the models to a separate project to be referenced in a xamarin cross-platform application. I created a .Net Core class library project to contain all the data models for each front end and included the ApplicationUser with an updated namespace into the project. I added the Microsoft.AspNetCore.Identity.EntityFrameworkCore nuget package to the library and reference the project from the Web application. The result produces the error below:

The problem capture

To fix this problem i had to revert the namespace of the ApplicationUser back to its original namespace from the Web Application. This seems to work for now but this was unexpected behaviour/bug?

Exact steps to reproduce the problem

Create ASP.NET Core Web Application with Individual User
Create .NET Core Class Library and add "portable-net452+win81" to the NetStandard1.5 imports and include "Microsoft.AspNetCore.Identity.EntityFrameworkCore" in the project.json
Move ApplicationUser to the class library and update namespace to correspond to class library
Reference class library from web application and update imports
Press Ctrl+F5 to run the application

.NET Core class library project.json

{
  "version": "1.0.1-*",

  "dependencies": {
    "NETStandard.Library": "1.5.0-rc2-24027",
    "Microsoft.AspNetCore.Identity.EntityFrameworkCore": "1.0.0-rc2-final",
  },

  "frameworks": {
    "net451": { },
    "netstandard1.5": {
      "imports": [
        "dnxcore50",

      ]
    },
    ".netcoreapp1.0": {
      "imports": [
        "dnxcore50",
        "portable-net45+win8"
      ]
    }
  },

  "scripts": {
    "postcompile": [
      "dotnet pack --no-build --configuration Debug -o ../../../packages"
    ]
  }
}

NOTE: I've included .netcoreapp1.0 to fix a resharper issue http://stackoverflow.com/a/37617711/3603938
