sdk: Microsoft.NETCore.App cannot be restored on projects with netstandard1.0, netstandard1.1, netstandard1.2, netstandard1.3, netstandard1.4.

Expectations

Microsoft.NETCore.App currently targets netstandard1.0 which lead me to believe it’d be possible (although not recommended) to use it in a >= netstandard1.0 project. However, it seems that the package is hand crafted and has dependencies that are inconsistent with its actual TFM.

Steps to reproduce

• Create a project with the project.json:

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "type": "platform",
      "version": "1.0.0-*"
    }
  },
  "frameworks": {
    "netstandard1.0": {
      "dependencies": {}
    }
  }
}

You can can change the netstandard1.0 tfm to 1.1, 1.2, 1.3 or 1.4 and get the same behavior

• Run dotnet restore

Expected behavior

• Restore completes successfully because Microsoft.NETCore.App’s nupkg says it targets netstandard1.0.

Actual behavior

• Restore fails because Microsoft.NETCore.App actually targets packages that depend on netstandard1.5

Environment data

.NET Command Line Tools (1.0.0-rc2-002678)

This seems like a blocker since the Microsoft.NETCore.App is the bread and butter to .NET core but I’ll let the higher powers decide.
