Cannot Run MVC6 App with dnx46 as a Framework with Reference to 4.6 Library

[MisterJames]

However, I am trying to use a project that was created with :

1. Updated global.json
2. Updated project.json (bumped all assemblies to Beta6)
3. Deleted/regenerated project.json.lock
4. Corrected EF errors (namespace moves, ValueGeneratedOnAdd, etc)
5. Removed ErrorPageOptions.ShowAll from middleware config

The app runs at this point. But I have the need to consume a 4.6 library, so, I:

1. Add a new ClassLibrary to the solution (Windows class library, targeting 4.6)
2. Add a reference from MVC project to ClassLibrary
3. Set framework to dnx46 in project.json

After saving project.json, references under dnx46 update correctly and restore.

At this point, I can no longer run the app. If I start with a debugger, I get a 500. If I start without debugging, I get the following:

The current runtime target framework is not compatible with 'WebApplication6'.

Current runtime Target Framework: 'DNX,Version=v4.5.1 (dnx451)'
  Type: CLR
  Architecture: x86
  Version: 1.0.0-beta6-12256

Please make sure the runtime matches a framework specified in project.json 

Installed, active/default on my machine:

Active Version     Runtime Architecture OperatingSystem Alias

       1.0.0-beta6 coreclr x64          win
       1.0.0-beta6 coreclr x86          win

Are there other bits I need to touch to get dnx46 working?

Looks like the wrap was correctly generated:

{
  "version": "1.0.0-*",
  "frameworks": {
    "net46": {
      "wrappedProject": "../../src/ClassLibrary1/ClassLibrary1.csproj",
      "bin": {
        "assembly": "../../src/ClassLibrary1/obj/{configuration}/ClassLibrary1.dll",
        "pdb": "../../src/ClassLibrary1/obj/{configuration}/ClassLibrary1.pdb"
      }
    }
  }
}

Solution layout looks like the following:

And here's the relevant bits from the project.json:

  "version": "1.0.0-*",
  ...
  "frameworks": {
    "dnx46": {
      "dependencies": {
        "ClassLibrary1": "1.0.0-*"
      }
    }
  },

And global.json looks like the following:

{
  "projects": [
    "src",
    "test",
    "wrap"
  ],
  "sdk": {
    "version": "1.0.0-beta6"
  }
}

Finally - and not sure if this helps - when I remove the DLL from the project, remove the dependency from project.json, and move back to dnx451, I noticed this warning:
Warning The primary reference "C:\Users\James\Documents\Visual Studio 2015\Projects\WebApplication6\src\ClassLibrary1\bin\Debug\ClassLibrary1.dll" could not be resolved because it was built against the ".NETFramework,Version=v4.6" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.5". WebApplication6 C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets 1819

Closing because I have a way easier repro.
