Can't build for net46 (net451, net452 works fine)

Steps to reproduce

Use the https://github.com/aspnet/cli-samples/tree/master/HelloMvc sample. Add net46 as the target framework Restore (restores fine) Build (dotnet build -f net46)

Expected behavior

Project builds successfully

Actual behavior

PS C:\Source\cli-samples\HelloMvc> dotnet build -f net46
Project HelloMvc (.NETFramework,Version=v4.6) will be compiled because expected outputs are missing

Thanks, @moozzyk. I came back to Core after 8-10 months. It seems I need to go to release notes and docs etc.

1. It works just fine for net451 and net452
2. Microsoft.NetCore.App is specific to netcoreapp1.0:

  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "version": "1.0.0-*",
          "type": "platform"
        }
      },
      "imports": [
        "portable-net45+wp80+win8+wpa81+dnxcore50",
        "portable-net451+win8"
      ]
    },
    "net46": {}
  },

1. If I did not separate Microsoft.NETCore.App - the error I get does not tell me that Microsoft.NETCore.App is causing the problem so the experience is bad.
