Can't publish netcoreapp1.0 if .NET/Mono not installed

Steps to reproduce

If a project.json contains both netcoreapp1.0 and netXXX targets it is impossible to publish the netcoreapp1.0 target when .NET Framework/Mono is not installed on the machine.

e.g. with project.json like this: https://github.com/aspnet/cli-samples/blob/098f56c4f677e64f0ffbeca3b1a8cde68787f499/HelloMvc/project.json#L22-L30

MacOS (I changed net451 to net461 because I have Mono already installed):

XXXX:HelloMvc Administrator$ dotnet publish -f netcoreapp1.0
The current project is not valid because of the following errors:
/Users/Administrator/source/cli-samples/HelloMvc/project.json(30,15): error DOTNET1011: Framework not installed: .NETFramework,Version=v4.6.1 in

Fedora:

[XXXX@localhost HelloMvc]$ dotnet publish -f netcoreapp1.0
The current project is not valid because of the following errors:
/home/moozzyk/source/cli-samples/HelloMvc/project.json(30,15): error DOTNET1012: The reference assemblies directory was not specified. You can set the location using the DOTNET_REFERENCE_ASSEMBLIES_PATH environment variable.

Windows (I changed net451 to net465 to get non-existing .NET Fx version - should it even restore?):

PS C:\Source\cli-samples\HelloMvc> dotnet publish -f netcoreapp1.0
The current project is not valid because of the following errors:
C:\Source\cli-samples\HelloMvc\project.json(30,15): error DOTNET1011: Framework not installed: .NETFramework,Version=v4.6.5 in

Expected behavior

When publishing for a specific framework other frameworks should be ignored

Actual behavior

Unable to publish

I have the same issue on a machine with .NET 4.6, where the project.json targets both net451 and netcoreapp1.0. For dotnet build, it fails if I don’t specify the target framework, but it works if I specify -f netcoreapp1.0. However, dotnet publish fails even if I specify -f netcoreapp1.0.

I’ve posted a workaround for this issue in the duplicate issue dotnet/sdk#6473 .
